Choosing the right booking engine for your hotel involves evaluating features, usability, support, and overall value. While both Amadeus’ iHotelier® Booking Engine and HotelSync’s Booking Engine aim to increase direct bookings, they serve different hotel profiles and operational needs.
Amadeus has a longer history, more extensive regional presence, and a larger review count but has recently seen no new reviews. HotelSync, with its fresher user base, boasts more recent feedback, higher ratings, and a more modern interface. Which one aligns better with your hotel's goals?
Both products target hotels seeking to improve online booking efficiency, but they approach this goal differently. Amadeus’s solution emphasizes integration with its broader ecosystem, including market intelligence and advanced pricing tools, making it suited for hotels with complex revenue strategies.
HotelSync, on the other hand, focuses on simplicity and guest experience, offering a straightforward setup with a mobile-optimized platform that appeals to hotels prioritizing ease of use and direct engagement. Do you need a comprehensive system with extensive integrations or a more streamlined, user-friendly platform?
If your hotel needs robust integration capabilities, especially with PMS, channel managers, and analytics, Amadeus is the better choice. Its large user base and extensive partner network support larger, multi-property, or tech-savvy hotels looking to maximize revenue.
If your hotel values simplicity, quick onboarding, and high user satisfaction, HotelSync is ideal. Its top-rated user experience, especially among smaller properties or those new to booking engines, makes it suitable for hotels prioritizing guest-centric workflows and straightforward management.
In summary, choose Amadeus if you prioritize advanced features and global presence; pick HotelSync if ease of use and recent positive reviews matter most.
HotelSync’s UI scores nearly perfect at 4.99/5, with many reviews highlighting its straightforward, intuitive design. Users praise its ease of learning, minimal clicks, and ability to manage reservations efficiently, even for non-technical staff.
Amadeus’s platform, with a rating of 4.25/5 for ease of use, is described as somewhat complex but manageable with proper onboarding. Some users mention a steeper learning curve and occasional usability challenges, especially with advanced functionalities.
Edge: HotelSync.

HotelSync provides 33 shared features plus 7 unique ones, such as social media integration/bookings, gift vouchers, pooled inventory, room substitutions, meal plans, Stripe, and customizable exit modals. These features cater well to hotels wanting flexibility, marketing, and upselling options.
Edge: Amadeus, for its more extensive suite of advanced, exclusive features.
HotelSync’s support scores a high 4.97/5, with reviews praising the responsiveness, friendliness, and clarity of their customer service. Users appreciate the easy onboarding and ongoing assistance, often mentioning quick resolution times.
Amadeus’s support, rated at 3.22/5, receives mixed reviews. Some users find the support helpful but note slow response times and difficulty resolving issues, which could impact hotel operations during critical moments.
Edge: HotelSync.
Amadeus boasts 104 verified partners, including prominent systems like SiteMinder, RevControl, and Profitroom, offering extensive connectivity options. This allows large hotels and chains to integrate seamlessly with their existing tech stacks.
HotelSync has 11 verified partners, including WuBook and GuestJoy. Its integrations focus on core booking functions, payment processing, and analytics but are more limited than Amadeus’s extensive network.
Edge: Amadeus.
HotelSync’s recent reviews show a perfect 5/5 rating from users in diverse segments, including small hotels and vacation rentals. The most recent feedback highlights its simplicity, reliability, and guest experience focus.
Amadeus, with a 4.39/5 overall rating, receives strong reviews but less recent activity. Its reviews often mention complexity and high costs as drawbacks but acknowledge its extensive features and global reach.
Edge: HotelSync.
Amadeus does not publicly list prices; it typically offers custom quotes based on hotel size and needs, often with a higher price point reflecting its enterprise capabilities.
HotelSync’s base price is $600/month, with no free tier or trial. Its transparent pricing makes it easier for hotels to assess ROI, especially smaller properties or those with tight budgets.
Not ideal if your hotel prefers a simple setup or operates on a tight budget.
Not ideal if you require extensive third-party integrations or complex revenue management tools.
Amadeus and HotelSync serve different hotel profiles with distinct priorities. Amadeus’s strength lies in its extensive feature set, integrations, and global presence, making it suitable for large, complex operations seeking revenue growth and market intelligence.
HotelSync excels in simplicity, user satisfaction, and affordability, making it ideal for smaller hotels or properties that value guest-centric workflows and quick deployment. If your hotel needs a feature-rich, scalable platform, Amadeus is the clear choice.
However, if ease of use, recent reviews, and support quality are more critical, HotelSync offers a compelling alternative. Ultimately, your choice should align with your hotel’s size, operational complexity, and strategic goals.
In conclusion, the product with more recent reviews and higher ratings, HotelSync, offers a more current and user-friendly experience. Its 83.3 HT score and 100% likelihood to recommend reflect strong confidence among its users, especially smaller hotels and boutique operations.
If your hotel seeks a highly integrated, feature-rich system and you’re prepared for a learning curve, Amadeus remains a solid candidate. But for most hotels prioritizing ease, support, and recent positive feedback, HotelSync stands out as the better option.

| 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?

Products with higher-quality integration ecosystems are more likely to deliver a connected tech stack. |
| Customer Centricity |
|
How customer-centric is this organization? Certified Support, Review Consistency, Profile Completeness ▾ Assesses whether the company has earned HTR Customer Support Certification, maintains consistent review collection over time (an indicator of feedback-driven culture), and keeps product profiles complete with capabilities, screenshots, pricing, and features. |
| 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. |
