RoomKeyPMS Booking Engine review
A direct-booking engine with flexible rates, packages, promotions, and abandonment recovery.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
RoomKeyPMS Booking Engine, also called eRes, lets hotel guests make direct reservations through a hotel website, with bookings passing into the connected RoomKeyPMS. Its mobile-friendly booking interface is aimed at hotels that want control over rates and offers within the direct booking flow. The product is available to RoomKeyPMS hotels, so it is not a fit for properties using a different PMS. Hotels of different sizes may be a fit, but the key requirement is the RoomKeyPMS connection.
Rate options go beyond a single nightly price: the engine supports daily, weekly, and monthly rates, along with discounted, membership, corporate, and negotiated group rates. Hotels can also present packages, inclusions, guest-service add-ons, and promotions such as free nights. Real-time reservation updates to the PMS keep the booking and property-management workflows connected. The booking-abandonment recovery tool and Google Analytics integration add ways to follow up on unfinished reservations and analyze performance. The integration set described is narrow, so hotels relying on a broader external booking ecosystem should assess that constraint before choosing it.
According to the vendor, eRes is included in onboarding for new RoomKeyPMS clients. Existing clients can contact sales about purchasing or customizing the engine after go-live; the vendor's public pricing page lists example hotel bundles but no prices. This makes the product more straightforward to consider alongside a new RoomKeyPMS deployment than as a separately priced add-on. The vendor lists email, phone, documentation, and ticket support, with 24/7 support, and states GDPR and PCI DSS compliance. Choose it if RoomKeyPMS is already central to hotel operations and rate flexibility or abandoned-booking recovery matters. Hotels that need a different PMS connection or a wider range of listed integrations should consider alternatives.
