AI Reservation Management System

My hotel’s booking flow needs an end-to-end AI layer that automatically looks after every reservation once a guest clicks “Book now.” The system must plug into the property-management / channel manager stack I already run and immediately take charge of three core jobs:

1. Send branded email confirmations the very second a reservation is created, then schedule follow-up reminder emails at configurable intervals.
2. Monitor inventory in real time, push rate changes when occupancy thresholds are reached, and keep every connected OTA perfectly in sync.
3. Accept cancellation or date-change requests, validate policy rules, update the room calendar, and trigger a fresh confirmation email.

Key requirements
• API-first architecture so it can sit between my PMS and channels like Booking.com, Expedia, and the direct-booking engine.
• Simple rule editor for rate and availability logic (e.g., close room types when only two left).
• Email templates editable in HTML with merge tags for guest name, stay dates, etc.
• Dashboard or log that shows every action the AI took, with the option to override manually when needed.
• GDPR-friendly data handling and clear error reporting.

Acceptance criteria
- A demo hotel account where I can simulate a new booking, see the immediate confirmation email, force a cancellation, and watch the calendar update.
- Code or cloud workspace handed over with setup instructions and any API keys abstracted.

If parts of the stack—language, framework, or specific AI services—can accelerate delivery, highlight those in your approach; I’m open to Python, Node.js, or comparable solutions as long as they stay maintainable.
