The Decision

Choosing between Guestline (Rezlynx PMS) and ThinkReservations PMS hinges on your hotel’s size, location, and operational needs. Both systems aim to streamline hotel management and boost revenue, but they diverge in scope, features, and global reach. Guestline offers a comprehensive, multi-country platform with extensive integrations, while ThinkReservations provides a simpler, highly rated user experience with a focus on North American properties. Which system best aligns with your goals?

Is Guestline (Rezlynx PMS) or ThinkReservations PMS Better for Hotels?

Guestline and ThinkReservations serve different hotel segments and scales but share the core goal of operational efficiency. Guestline’s platform, used in 20 countries, offers an end-to-end suite with a deep focus on large or expanding independent and boutique hotels, particularly in Europe and Asia Pacific. In contrast, ThinkReservations specializes in small to medium properties, predominantly in North America, focusing on simplicity and ease of use.

Guestline boasts a broader feature set—38 shared features plus 13 exclusive—such as revenue management, guest CRM, and multi-lingual support, making it suitable for hotels seeking advanced automation and integration. ThinkReservations offers an even more streamlined experience, with only one exclusive feature (Shift Planning), but excels in OTA integration and intuitive design. Do you prefer a comprehensive global platform or a straightforward system tailored for small operations?

Guestline vs ThinkReservations: Which Should Your Hotel Choose?

If your hotel needs robust, multi-lingual, multi-currency solutions with extensive third-party integrations and a multi-region footprint, Guestline is the clear choice. Its detailed modules support large-scale operations, conferences, and complex revenue management, making it well-suited for independent hotels seeking growth and international reach.

If your hotel prioritizes ease of use, rapid onboarding, and reliable OTA connectivity within North America, ThinkReservations is the better fit. It’s ideal for small to mid-sized inns, B&Bs, and boutique hotels aiming to automate reservations and maximize revenue with minimal complexity. For hotels focused on growth in the US, ThinkReservations offers a straightforward, high-rated solution with excellent support.

Is Guestline (Rezlynx PMS) or ThinkReservations PMS Easier to Use?

ThinkReservations boasts a higher ease of use rating—4.82/5 compared to Guestline’s 4.47/5—and reviews consistently highlight its user-friendly interface. Customers praise ThinkReservations’ simple onboarding process, intuitive booking engine, and straightforward management tools, making staff adoption quick and training minimal.

Guestline, rated at 4.47/5, provides a feature-rich interface that some users find complex at first. Its onboarding is rated slightly lower at 4.21/5, and some reviews mention a learning curve due to its extensive modules. Edge: ThinkReservations.

Which Has Better Features: Guestline or ThinkReservations?

Guestline offers a total of 38 shared features plus 13 exclusive modules, including revenue management, guest CRM, online checkout, and multilingual support. Its comprehensive suite supports complex hotel needs like conference management and integrated digital marketing.

ThinkReservations provides 38 shared features but only one exclusive feature—Shift Planning—highlighting its focus on simplicity. Its strengths lie in OTA integrations, automated messaging, and upselling tools, with fewer advanced modules but high reliability. Edge: Guestline, for its extensive feature set.

Which Has Better Customer Support: Guestline or ThinkReservations?

ThinkReservations consistently receives high praise for support—rated at 4.82/5—and reviews emphasize quick, helpful responses and attentive service. Hoteliers describe their experience as adding “another employee” in terms support quality and accessibility, especially beneficial for small teams.

Guestline’s support ratings are slightly lower—4.41/5—and some users report slow response times and inconsistent service, especially during system issues. While support is generally good, reviews suggest room for improvement, particularly with support responsiveness during upgrades and bugs. Edge: ThinkReservations.

Which Has More Integrations: Guestline or ThinkReservations?

Guestline supports 95 verified integrations, including well-known partners like TrustYou, Triptease, Tripadvisor, and Airbnb, making it highly adaptable for large properties or groups with diverse software needs. It also offers numerous integrations specific to revenue management, CRM, and online marketing.

ThinkReservations offers 16 verified integrations, mainly with OTAs such as Booking.com, Expedia, and Airbnb, plus a few niche tools like Stripe and OpenKey. While fewer in number, these integrations are highly reliable and sufficient for small hotels focused on direct booking and OTA distribution. Edge: Guestline.

Guestline’s ratings are slightly lower at 4.53/5, with older reviews reflecting satisfaction with features but some concerns about support and system complexity. Both products are well-rated, but ThinkReservations’ recent reviews give it a slight edge in current customer satisfaction.

How Much Do Guestline and ThinkReservations Cost?

Guestline does not publicly list its pricing, emphasizing a tailored quote based on hotel size and needs, typical for enterprise-level systems. ThinkReservations charges a flat $500 monthly fee, with no setup or implementation fees, making its costs transparent and predictable for small to mid-sized hotels.

If your hotel is budget-conscious or prefers clear pricing, ThinkReservations provides straightforward, predictable costs. Guestline’s bespoke pricing may suit larger hotels or hotel groups with complex requirements, but it’s less transparent.

What Type of Hotel Should Use Guestline?

  • Hotels that operate across multiple countries and require multi-lingual, multi-currency support.
  • Hotels with conference, event, or group management needs.
  • Larger independent hotels or hotel groups seeking extensive automation and integrations.
  • Hotels planning expansion or international marketing campaigns.

Not ideal if your hotel is small, in North America, and prioritizes simplicity. This system’s complexity and regional focus might be overwhelming for boutique or small inn operators.

What Type of Hotel Should Use ThinkReservations?

  • Small to medium-sized hotels, inns, B&Bs, and boutique hotels, primarily in North America.
  • Properties seeking a quick, easy-to-implement PMS with reliable OTA connectivity.
  • Hotels aiming to increase revenue through upselling and automated communication.
  • Operators who value excellent support and transparent pricing.

Not ideal if your hotel requires extensive multi-language, multi-currency options, or advanced revenue management modules. Larger hotel chains or properties outside North America may find it limiting.

Guestline vs ThinkReservations: The Bottom Line for Hotels

Guestline offers a comprehensive, multi-country property management platform with numerous integrations and advanced modules. It suits hotels seeking a broad solution for complex operations, international marketing, and revenue management.

ThinkReservations excels in simplicity, support, and OTA integrations—making it ideal for small hotels focused on direct bookings and operational efficiency in North America. Its high user ratings and recent reviews point to a product that’s easy to adopt and effective.

If your hotel needs extensive automation, multi-region support, and a wide array of features, Guestline is the better choice. For small hotels prioritizing ease, support, and cost transparency, ThinkReservations is the smarter pick.

In conclusion, for most U.S.-based small to mid-sized hotels, ThinkReservations’ recent reviews, high ratings, and straightforward approach make it the stronger candidate. Larger, international hotels with complex needs should lean towards Guestline for its breadth of features and global reach.
