RoomKeyPMS Booking Engine vs ThinkReservations Booking Engine

RoomKeyPMS Booking Engine, or eRes, lets hotel guests reserve rooms online through a hotel's website. It supports daily, weekly and monthly rates, membership and corporate rates, group blocks, packages, add-ons, promotions and free-night offers. Hotels can link to eRes or add a Book Now or Reservations button, and RoomKeyPMS can apply brand colors, fonts, banners and logos during onboarding. The maker describes the engine as mobile-ready, with reservations passing instantly into the PMS. It says reservations update the PMS in real time and inventory adjusts across other channels to help avoid overbooking. Listed tools include OTA price comparison, dynamic packaging, language translation, recovery messages, alternative offers, locked deals, flexible-date calendars and layout choices. Integrations include Booking.com, Expedia, Guestfolio, Duetto, IDeaS RMS, SiteMinder, SynXis, TravelClick/iHotelier and Vertical Booking. The web product requires RoomKeyPMS; it is included in onboarding for new clients. Pricing is on request, including for purchase or customization after go-live.

ThinkReservations Booking Engine displays rates and availability to lodging guests, with the aim of supporting direct reservations. The booking experience can be customized to match a property's website and supports mobile bookings. Properties can set single-night, customer-group, seasonal, and member rates, run promotions, and apply automatic rule-based rate adjustments. The engine can collect deposits, create tasks from reservation add-ons, update third-party channels, and send guest emails and texts. Listed connections include Airbnb, Booking.com, Expedia, Tripadvisor, PriceLabs, Google Hotel Ads, and Micros-interface POS systems. An August 2026 update added booking-flow translations and automated bot protection at registration, enabled by default. ThinkPayments uses Stripe infrastructure; card data is tokenized and stored in Stripe's PCI-DSS Level 1 environment. 3D Secure is supported for SCA-regulated transactions and high-risk bookings. The service includes account configuration and staff training, plus on-demand knowledge articles and webinars. Its External API lets partners access reservations, availability, rates, rooms, room types, and inventory, and create reservations. Pricing is available on request.
