When evaluating direct booking tools, your primary concern is which platform will most effectively increase bookings while providing a user experience your team and guests will appreciate. Both The Guestbook and Gustaffo Reservation Management aim to optimize reservations, but they approach this goal differently—one through guest rewards and loyalty, the other through AI-driven insights and streamlined booking management. Which aligns better with your property’s strategic goals?
The Guestbook, with its focus on cash-back rewards and proven ROI, has a significant edge due to its extensive verified user base and recent positive reviews. Gustaffo’s reservation system, meanwhile, offers AI-powered insights but lacks recent reviews and a broad user base, making it harder to judge its real-world effectiveness. So, which of these solutions will truly deliver the revenue lift you seek?
Both products target increasing direct bookings, yet their methods differ sharply. The Guestbook emphasizes guest engagement through cash rewards, aiming to directly incentivize bookings and foster loyalty, while Gustaffo relies on AI to refine offers and optimize booking flows based on customer behavior.
The Guestbook’s users consistently report increased conversions, with hotels achieving up to 40% boosts in direct bookings and notable revenue growth, backed by over 175 recent reviews. Gustaffo’s approach, with only two verified integrations and no recent reviews, lacks the same proven track record.
Given the extensive recent positive feedback, The Guestbook’s model appears more reliable for hotels seeking immediate results. Are you prepared to prioritize a reward-driven approach that’s backed by a large, recent review corpus?
If your hotel needs to boost direct booking conversions and build long-term loyalty through tangible rewards, go with The Guestbook. Its proven track record in generating increased revenue, with over 175 reviews and a 4.91/5 customer support rating, makes it a dependable choice. The platform’s ease of use (4.82/5) and high NPS score (9.68/5) reflect strong hotelier satisfaction.
If, however, your team seeks a reservation management system driven by AI insights to personalize offers and streamline booking operations, Gustaffo might appeal. But with no recent reviews or a large user base, its actual impact remains unverified.
For most hotels aiming to grow direct bookings effectively today, The Guestbook’s strategies offer a more immediate, validated path.
The Guestbook scores an impressive 4.82 out of 5 for ease of use, supported by positive reviews praising its intuitive interface for both staff and guests. Users highlight straightforward onboarding, with many noting how quickly their teams adopted the platform and started seeing results.
Gustaffo’s user experience details are unavailable, and with no recent reviews to gauge client satisfaction or onboarding success, it’s impossible to compare directly.
Edge: The Guestbook.
The Guestbook offers 5 core features, including its Cash Rewards Suite, Reward Dash portal, and unique Parity Reports and Messaging Analytics—tools that directly enhance guest engagement and data insights. Gustaffo provides only 2 verified integrations—Stripe and its own reservation system—and offers 4 features centered on AI-driven insights and offer tracking.
The Guestbook’s added features, especially its analytics and reporting tools, provide tangible benefits for hoteliers looking to understand and improve guest loyalty. Gustaffo’s AI features, while promising, lack depth and recent validation.
Edge: The Guestbook.
The Guestbook has a strong reputation for customer support, with a 4.91/5 rating and recent reviews praising its quick, helpful assistance. Users describe support as responsive and vital during challenging times, reinforcing confidence in onboarding and ongoing use.
Gustaffo’s support and onboarding ratings are unavailable, and with no recent reviews or case studies, there’s no way to assess its support quality.
Edge: The Guestbook.
The Guestbook boasts 36 verified partners, including prominent hotel tech providers like WebRezPro, ROIBACK, and The Hotels Network, ensuring broad compatibility. Gustaffo’s system is limited to just 2 verified partners, Stripe and its own reservation platform, restricting integration possibilities.
More integrations mean easier system interoperability and a more unified tech stack, which The Guestbook clearly supports.
Edge: The Guestbook.
The Guestbook’s ratings reflect high satisfaction, with a 5/5 overall rating and a 4.91/5 customer support score, based on 175 recent reviews. Hotels of various segments, especially boutique, luxury, and resort properties, consistently praise its results and ease of use.
Gustaffo lacks recent reviews and a rating score, making it impossible to determine hotel satisfaction or reputation.
Edge: The Guestbook.
The Guestbook’s pricing starts at $200 per month, with no free tier or implementation fees, making its costs predictable and transparent. Gustaffo’s base price is slightly higher at $300 monthly, but detailed pricing structures are not publicly available, limiting precise comparisons.
Considering the proven ROI and extensive support, The Guestbook’s transparent pricing offers better value for money.

The Guestbook offers a well-validated, reward-driven approach to increasing direct bookings, with a long list of happy clients and recent reviews confirming its effectiveness. Its extensive features, integrations, and excellent support make it a solid choice for hotels aiming for tangible revenue growth and guest loyalty.
Gustaffo, with its AI-driven reservation focus, might appeal to tech-savvy teams looking to optimize booking processes but lacks recent validation and a broad user base. Its impact remains unverified in the current market landscape.

The HT Score is a composite ranking that considers 4 criteria groups and over a dozen variables to help hoteliers objectively compare hotel technology products. The Guestbook has an HT Score of 96 and Gustaffo digital Service GmbH has 0. Here is how the score is calculated.
| 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? Partner Recommendations, Integration Quantity, Integration Quality ▾ Evaluates partner recommendations as expert votes of confidence, the number of verified integrations, and ecosystem quality — the average HT Scores of integration partners. 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. |
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 →
