RoomKeyPMS Booking Engine

RoomKeyPMS Booking Engine, branded eRes, is a web booking engine for hotels that want guests to reserve directly through the property website. It suits independent hotels already using RoomKeyPMS best. Its strongest case is the connection between direct reservations and PMS inventory; it is not a standalone fit for hotels without RoomKeyPMS.

Overview

A hotel can connect eRes to its website using a booking link or a Book Now or Reservations button. During onboarding, RoomKeyPMS can apply the property’s colors, font, banner, and logo. That gives the booking path room-specific branding without requiring the hotel to build a separate booking site.

eRes supports daily, weekly, and monthly rates, as well as membership and corporate rates, group blocks, packages, add-ons, promotions, and free-night offers. This breadth helps hotels accommodate different stay lengths and guest segments. The engine is part of a broader RoomKeyPMS workflow, however, rather than an independent reservation product.

Key features

Booking options and distribution

RoomKeyPMS lists OTA price comparison, dynamic packaging, language translation, recovery messages, alternative offers, locked deals, flexible-date calendars, and layout choices among eRes’s advanced features. Together with its rate and promotion options, these give hotels ways to present varied booking scenarios. The product description does not establish how each option is configured, so hotels with a specific booking-flow requirement should confirm that during evaluation.

RoomKeyPMS says online reservations pass instantly into the PMS and that inventory updates across other channels in real time to help prevent overbooking. That makes eRes particularly relevant to RoomKeyPMS properties seeking to keep direct bookings and channel inventory in sync. Its integrations include Booking.com, Expedia, Guestfolio, Duetto, IDeaS RMS, SiteMinder, SynXis, TravelClick/iHotelier, and Vertical Booking. Development teams can also use the API to connect web-based systems to the PMS.

Mobile, privacy, and support

RoomKeyPMS describes eRes as mobile-ready, an important consideration for guests booking from phones. It says the product is PCI 3.2 compliant and provides its Attestation of Compliance certificate upon request. Guest privacy features cover opt-in, opt-out, and data-removal procedures intended to support GDPR compliance.

Support includes email and phone assistance, 24/7 emergency phone support, and a knowledge base available around the clock. This is useful for hotel operations that need an emergency contact path, though the available plan information does not distinguish support by tier.

Pricing

eRes Booking Engine: custom pricing, available with each RoomKeyPMS database and requiring RoomKeyPMS. The engine is included in onboarding for new RoomKeyPMS clients. Hotels considering a purchase or customization after go-live must contact sales for pricing.

That makes eRes a natural option for properties already adopting RoomKeyPMS, but less straightforward for hotels comparing standalone booking engines on a published budget. There is no separate eRes plan described for use without the PMS.

Platforms

eRes is a web product. RoomKeyPMS says reservations pass from the mobile-ready booking engine into the PMS instantly, but the stated platform is web rather than a separate mobile app.

Who it's for

eRes is aimed at hotels that want direct website bookings connected to RoomKeyPMS, particularly independent properties using its reservation and channel inventory workflow. RoomKeyPMS says it serves independent hotels and manages more than 70,000 rooms across North America; the company also says it has operated for 20 years.

Hotels that need a booking engine independent of RoomKeyPMS should look elsewhere. Likewise, teams that require a published price before engaging sales may prefer an option with transparent plan pricing.

Pros and cons

• Pros: A broad mix of rate types, packages, promotions, and booking options supports more than standard nightly reservations.
• Pros: Real-time PMS and channel inventory updates are designed to help reduce overbooking for RoomKeyPMS properties.
• Pros: Website branding, mobile-ready bookings, API access, and named integrations offer several ways to fit eRes into a hotel’s booking workflow.
• Cons: RoomKeyPMS is required, so hotels seeking a standalone engine are not a match.
• Cons: Pricing for purchase or customization after go-live is custom, which makes advance cost comparison harder.

Verdict

Choose eRes if your hotel already uses RoomKeyPMS and wants direct website bookings tied to PMS reservations and channel inventory. Its broad offers and real-time inventory updates are the main reasons to choose it. Look elsewhere if you need a standalone booking engine or need a published price before starting a sales conversation.
