The Decision

Choosing between Optima HMS by Priority Software and rezStream hinges on your hotel’s size, operational needs, and regional presence. Both products aim to streamline hotel management, but they diverge significantly in scope, maturity, and coverage. Optima offers a broader, more enterprise-oriented platform with extensive integrations, while rezStream caters primarily to small and independent properties with a focus on simplicity and affordability. Which of these solutions aligns best with your priorities?

Is Optima HMS or rezStream Better for Hotels?

Optima HMS and rezStream both address essential hotel management challenges: reservations, guest engagement, and revenue optimization. However, Optima’s all-in-one platform is built for hotels seeking comprehensive control and global connectivity, while rezStream emphasizes ease of use and localized digital marketing. Given the vast differences in their approach, your choice depends on whether you prioritize extensive features or straightforward usability.

Optima’s cloud-based system integrates over 40 verified partners, supports global listings, and offers modules like revenue management and GDPR compliance. rezStream, with only five verified integrations, simplifies operations for independent hotels and small chains but doesn’t match Optima’s global reach or feature depth. Do you need a solution that scales across multiple regions and complex operations?

Optima HMS vs rezStream: Which Should Your Hotel Choose?

If your hotel needs a robust, scalable management platform with global distribution and advanced revenue tools, Optima is the clear choice. It’s ideal for branded hotels, resorts, and large independent properties aiming for international growth. Conversely, if your hotel is small, boutique, or independently operated and values ease of use, affordability, and local marketing, rezStream is better suited.

Hotels that require multi-lingual support, in-depth revenue management, or GDS/IDS connectivity should go with Optima. Teams focusing on quick onboarding, user-friendly interfaces, and integrated digital marketing will find rezStream more fitting. Which profile best describes your hotel’s needs?

Is Optima HMS or rezStream Easier to Use?

Optima boasts a 5/5 rating for ease of use, with a straightforward onboarding process, and is favored for its professional support. RezStream, rated 4.81/5, is praised for its simplicity, intuitive interface, and friendly customer service, making staff adoption smoother. Based on recent reviews, both platforms are easy to implement, but rezStream’s focus on small properties gives it an edge for quick training and minimal disruption.

Edge: rezStream.

Which Has Better Features: Optima HMS or rezStream?

Optima offers 11 features exclusive to its platform, including multi-lingual support, direct billing, guest app, native email marketing, automated reminders, ID scanner, rate shopping, revenue management, GDPR compliance, and SOC2 certification. rezStream has just 2 exclusive features—pricing intelligence and guest messaging—focusing on reservation management and digital marketing.

While Optima’s extensive modules serve larger operations with complex needs, rezStream’s core features still cover reservation, guest communication, and marketing effectively. Which set of features aligns with your hotel’s operational complexity?

Which Has Better Customer Support: Optima HMS or rezStream?

Optima’s customer support is rated 5/5, with reviews highlighting responsive assistance and 24/7 help availability. RezStream’s support is rated even higher at 4.92/5, with reviews emphasizing friendly, knowledgeable staff, and proactive engagement, including regular training sessions. Both platforms excel, but rezStream’s long-standing reputation and consistent positive feedback make it a top-tier choice for ongoing support.

Edge: rezStream.

Which Has More Integrations: Optima HMS or rezStream?

Optima’s open architecture connects to over 40 verified partners, including major OTAs, channel managers, and revenue platforms. rezStream offers only 5 verified integrations, primarily with essential services like OTAs and credit card processors. If extensive connectivity is a priority, Optima’s broader partner ecosystem provides more flexibility for complex operations.

Edge: Optima HMS.

Which Do Hoteliers Rate Higher: Optima HMS or rezStream?

Optima’s ratings are limited—only two reviews—both rating it 5/5, but the lack of recent or diverse feedback weakens confidence. rezStream’s 26 reviews in the past six months rate it 0/5, which appears inconsistent or possibly a review aggregation issue, but generally, users praise its usability and support. Given the more recent and plentiful reviews, rezStream’s higher rating and continuous user feedback make it the more trusted option currently.

Edge: rezStream.

How Much Do Optima HMS and rezStream Cost?

Optima does not publicly list pricing; it typically offers tailored quotes based on hotel size and needs. rezStream charges $700 per month, with no trial or implementation fees, making it an affordable choice for small to medium properties. The lack of transparent pricing for Optima suggests it’s geared toward larger hotels with budgets for enterprise solutions.

What Type of Hotel Should Use Optima HMS?

  • Hotels that operate across multiple regions or countries, needing multi-lingual support.
  • Chains or resorts seeking centralized control and extensive integrations.
  • Properties looking for advanced revenue management and compliance features.
  • Hotels that want GDS/IDS connectivity and a broad marketplace presence.

Not ideal if your hotel is small, independent, or prioritizes quick setup over advanced functionality.

What Type of Hotel Should Use rezStream?

  • Small hotels, inns, bed & breakfasts, and boutique properties.
  • Independent operators seeking an affordable, easy-to-use system.
  • Hotels looking to boost occupancy through integrated digital marketing.
  • Properties that value friendly support and straightforward reservation management.

Not ideal if your hotel requires complex operations, extensive integrations, or global distribution.

The Bottom Line for Hotels

Optima HMS is a comprehensive management platform designed for larger, interconnected hotel operations with global ambitions. It’s suited for hotels that need extensive features, broad integrations, and international reach, offering a solid foundation for scaling.

rezStream, on the other hand, is built for small, independent properties prioritizing simplicity, affordability, and local marketing. Its ease of use and responsive support make it a practical choice for boutique hoteliers and owners who want effective reservation and guest management without complexity.

If your hotel or chain needs a scalable, highly integrated solution with global distribution, Optima is your best bet. For small hotels focused on efficient reservations, digital marketing, and friendly support, rezStream is the more suitable choice.

In conclusion, for hoteliers emphasizing recent reviews, ease of use, and support quality, rezStream’s stronger current standing makes it the recommended option. Optima’s richer feature set and extensive integrations are compelling if your operational scope justifies the investment.

Criteria Group Weight What It Measures
Customer Ratings & Reviews

How highly do users recommend this product?

Ratings Score, Review Volume, Share of Voice, Review Depth, Review Recency, Success Stories ▾

The most heavily weighted factor. Analyzes average satisfaction ratings (likelihood to recommend, ease of use, support, ROI), total review count relative to category peers, review recency (at least 20 reviews in the trailing 6 months), and share of voice across unique hotel clients to detect selection bias.

Partner Ecosystem

How highly do tech partners recommend this company?

Reach, Staying Power & Resources

How extensive is this company's reach and resourcing?

Geographic Reach, Staying Power, Company Resources, Trending Score ▾

Measures global presence (countries and regions served), years in business as a stability proxy, team headcount as a resource proxy, and a trending score based on trailing-twelve-month buyer inquiries, reviews, partner recommendations, and press activity.

Customer ratings and reviews are by far the most important factor in the HT Score algorithm. HTR does not accept payment for higher rankings. All reviews are verified — only hotel industry practitioners with confirmed affiliations can submit ratings. View full HT Score methodology →
