Every feature

The full Hydra Booking Engine feature list

Beyond the highlights — everything the widget and dashboard do, organized by category.

Hydra Booking Engine v1.7

Self-contained embeddable widget — no iframe, no external CSS/JS dependencies, scoped styles that won't clash with the host page
Multi-room cart — up to 8 rooms per booking, each with its own occupancy
Scarcity messaging shown only at 3 or fewer rooms left — never exposes raw inventory otherwise
3-language UI (English, German, Hungarian) with auto-detection and a guest switcher
Booking reference codes with a hotel-configurable prefix (e.g. HYD0001)
Company/business booking toggle capturing company name, tax number, and billing address for invoicing
Per-room extras/upsells at checkout — a pet fee or breakfast can be added to just one room in a multi-room booking, not the whole cart
A hosted booking page for hotels that want one — the hotel's own link and QR code, wearing the hotel's branding
Room cards that lead with a cover photo and stack the description and options below at full width, so a long description never breaks the layout; a group of room types shows its members' photos and tags
Check-in and check-out times and the hotel's address, as a map link, on the booking and confirmation pages
A booking window: guests can book at most 365 days ahead, and a change request can never ask for a past date
A waiting list for sold-out dates (guests are emailed when a room opens) and guest change requests, both answered from the dashboard

Season-based pricing synced from PMS rate codes, including year-wrap seasons
Dynamic yield pricing by live occupancy band, dashboard-overridable
Per-person occupancy surcharges for extra adults, teens, children, and infants
Promo codes with usage caps, minimum-stay rules, and date-validity windows
Direct-channel revenue tracking with a commission-saved-by-going-direct calculator
Per-offer or hotel-wide price adjustments (percent or fixed) independent of promo codes — e.g. a non-refundable rate priced automatically lower
Minimum stay by arrival weekday, set in the dashboard

OTP SimplePay integration — Hungary's dominant gateway, HUF-native, no third-party SDK dependency
Sandbox and production modes, switchable per hotel or platform-wide
Four payment policies per rate code: hold, deposit, full charge, or bank transfer
Automatic hold release on cancellation; capture always requires an explicit refund action
Abandoned-checkout recovery email and automatic stale-hold expiry
Bank transfer as the guest's own choice next to the card, with a payment deadline of 1–30 days: the guest writes the PMS reservation number in the transfer, reception records “transfer received” (the guest gets a receipt) or extends the deadline, and a booking still unpaid at the deadline is cancelled

Staff accounts separate from the PMS license key, with self-service password reset and login rate-limiting
Send guests real quotes for groups and flexible dates, with an expiry and an accept/decline link
Promo code and upsell management, effective immediately with no PMS sync needed
Rate and room-type content editors — descriptions, photos, cancellation policy — layered on top of PMS pricing
Manual reputation log for staff-entered reviews
A redesigned dashboard — Home with a setup checklist, Bookings (search, open, cancel, resend, CSV export), a Calendar of occupancy and lowest price per day, Guests with VIP flags, Rates & offers, and Settings
The PMS invites the hotel's owner by email: they choose a password and are signed straight in — nobody has to find a licence key — with a list of signed-in devices and per-device sign-out

Bidirectional sync: rate codes, room types, and seasons pushed on change; availability pushed every 5 minutes
Auto-registration on the first sync call — no separate signup step
Confirm/reject workflow for pulling web bookings into the PMS, with idempotent guest confirmation emails
Multi-room bookings map to a single PMS reservation when supported
Two-way cancellation reconciliation — a guest self-cancel releases the room in the PMS, and vice versa
The payment state of every web booking (paid, card hold, awaiting transfer) is readable from the PMS, which can capture or release a card hold from the reservation

Consent banner plus a required, client-side-enforced checkbox at booking submission
Consent recorded per booking as part of its own audit trail
No-login guest data export (immediate) and deletion request (staff-reviewed)
Staff dashboard for pending deletion requests, with a true-anonymize action (covering company/billing fields too) that preserves accounting history

Custom domain support — guest-facing links run on the hotel's own domain, including the payment redirect
One modern widget style that takes the hotel's primary and secondary brand colours and a light, dark or auto mode, with a live preview of the real booking page in the dashboard
CORS allowlist so the widget only runs on approved domains
Everything a guest sees can wear the hotel's branding: logo, cover picture, tab icon, share text, the wording of the booking form in three languages, “why book direct” lines, legal links and a thank-you page
Booking emails from the hotel's own sender name, with its header style, footer note and social links, and a “before you arrive” text added once the booking is confirmed
