The Decision

Choosing between Diamo by Diamo and happyhotel by happyhotel for your hotel's revenue management requires understanding their core differences, strengths, and weaknesses. Both systems aim to optimize your revenue, but they do so with distinct approaches, features, and levels of user adoption. Your decision hinges on which platform aligns best with your property size, operational needs, and growth plans.

Diamo and happyhotel both aim to increase your revenue through automation and smarter pricing, but they target different hotel segments and offer varying depths of features. Do you need a solution that is more comprehensive with a focus on boutique and independent hotels? Or one that offers broader automation with extensive integrations for larger properties? Let's explore.

Is Diamo or happyhotel Better for Hotels?

Diamo and happyhotel both serve revenue management functions, but their data backing and user feedback tell different stories. Diamo, with only 24 reviews—none in the last six months—struggles with a low overall rating and limited recent feedback to validate its claims. Conversely, happyhotel boasts 151 reviews, with 63 in the last six months, and enjoys a significantly higher rating of 92.5 compared to Diamo’s 71.5 HTR Score, making it the more reliable choice in terms of user satisfaction.

Diamo’s reviews highlight strengths like budget-friendly customer support and effective rate management but also reveal issues like data syncing delays and limited advanced features. Happyhotel, however, is praised for its automation, deep integrations, and ease of use, especially among small to medium-sized hotels. Do recent reviews and high ratings make happyhotel the more dependable option? The evidence points there.

Diamo vs happyhotel: Which Should Your Hotel Choose?

If your hotel is a boutique property or an independent hotel seeking a straightforward, user-friendly RMS that emphasizes manual control and strategic input, Diamo might be a fit. Its focus on market insights and enterprise guidelines makes it suitable for properties that want transparency and guidance without overly complex automation.

However, if your hotel needs robust automation, extensive integrations with PMS and channel managers, and features like scenario analysis and forecast building, happyhotel is the clear winner. Its 151 reviews and recent scores support its reputation for automating revenue management effectively, making it ideal for properties that want to scale and streamline with minimal manual effort. For most small to midsize hotels, happyhotel is the more comprehensive solution.

Is Diamo or happyhotel Easier to Use?

Diamo’s UI is praised for its simplicity, with a 4.83/5 rating, and many reviewers mention how easy it is to navigate and set up. Support is also highly rated at 4.96/5, with users highlighting their positive onboarding experiences. However, some reviews suggest that the dashboard could benefit from more intuitive features, especially in real-time data visualization.

Happyhotel’s interface scores slightly lower at 4.77/5 but is still highly regarded for its clarity. Reviewers appreciate its user-friendly design, quick onboarding, and seamless PMS integrations, making daily operations smoother. Given the recent positive reviews and high support ratings, the edge goes to happyhotel for overall ease of use.

Which Has Better Features: Diamo or happyhotel?

Diamo offers 16 shared core features plus three unique ones, including Price Explanation, Enterprise Business Guidelines, and Market Insights Reporting. These features are beneficial for small teams wanting guidance and market perspective but lack automation-heavy tools.

happyhotel, however, provides 29 unique features, including open API, full automation, scenario analysis, multi-property dashboards, and 18-month forward pricing. It supports advanced automation, detailed forecasting, and flexible customization. The sheer number of features and automation tools give happyhotel a clear edge for properties seeking full control and scalability.

Which Has Better Customer Support: Diamo or happyhotel?

Diamo consistently garners praise for its customer support, with a 4.96/5 rating and reviews describing their team as accommodating and responsive. Many users mention that support is available when needed and that staff often guide them through strategy adjustments effectively.

happyhotel’s support is also well-rated at 4.81/5, with reviewers describing their customer service as personal and quick. However, Diamo’s support scores slightly higher and receives more recent positive feedback, indicating a more reliable support experience overall. The edge goes to Diamo in support quality.

Which Has More Integrations: Diamo or happyhotel?

happyhotel offers 24 verified integrations, including popular systems like RoomRaccoon, apaleo, and protel. Shared integrations include Mews, Little Hotelier, and SiteMinder. This extensive network enables seamless data flow across systems, making automation and data accuracy easier to achieve.

Diamo has only 7 verified integrations, with shared partners like Mews and SiteMinder but limited exclusive connections. While suitable for smaller setups, Diamo’s fewer integrations may restrict broader automation. The clear winner in integrations is happyhotel.

Which Do Hoteliers Rate Higher: Diamo or happyhotel?

Hoteliers rate happyhotel significantly higher, reflected in its 92.5 score and 151 recent reviews, mostly praising automation, support, and ease of use. Reviewers mention improvements in workflow, revenue, and data insights, with many indicating it’s suitable for their property size and complexity.

Diamo’s reviews, however, are sparse and outdated, with no recent feedback to support current performance. Its overall rating of 0/5, based on limited and old reviews, makes it a less reliable choice. Clearly, happyhotel is the hotelier-favored product.

How Much Do Diamo and happyhotel Cost?

Diamo’s pricing is a flat $600 per month, with no trial or freemium options. happyhotel’s base price is $500 per month, also without a free trial. Neither platform publicly offers tiered pricing; costs are straightforward but may vary with customizations.

Considering the features and recent reviews, happyhotel’s slightly lower price combined with more recent user satisfaction offers better value for most hotels. However, your hotel’s specific needs may influence the choice if budget is a primary concern.

What Type of Hotel Should Use Diamo?

  • Hotels that prefer guidance and manual control over their revenue strategies.
  • Boutique hotels or independent properties seeking straightforward insights and basic market reporting.
  • Teams that want a cost-effective solution with high customer support ratings.
  • Not ideal if:
    • You require extensive automation and integration.
    • Your property is a large chain or resort needing advanced forecasting tools.
    • You need real-time market comparison features or extensive data syncing.

Diamo vs happyhotel: The Bottom Line for Hotels

Diamo and happyhotel serve the same goal—maximizing revenue through smarter pricing—but differ significantly in maturity, features, and user feedback. Diamo, with no recent reviews and a lower overall rating, appears less suited for hotels seeking proven automation and extensive integrations.

Happyhotel, backed by 151 reviews and recent positive feedback, stands out for its automation, integrations, and ease of use. For most small to midsize hotels looking to streamline revenue management, happyhotel is the recommended choice.

If your hotel needs a flexible, automation-driven system that integrates deeply with your existing tech stack, go with happyhotel. Its feature set and recent user satisfaction make it the smarter investment for property owners focused on growth and operational efficiency.

If, however, your property prefers a guided approach with basic insights and manual control, Diamo may suffice, but its limited recent feedback warrants caution. Overall, happyhotel is the more reliable choice for most hotels today.
