TL;DR — Hotel Booking System

Design a hotel booking platform like Booking.com that allows users to search for hotels by location, dates, and guest count, view available rooms with pricing, and complete bookings with instant confirmation. The system must handle complex availability calendars where room inventory changes by the minute as bookings and cancellations flow in. Key features: Search hotels by location, check-in/out dates, guests, rooms. View hotel details with room types, photos, amenities, reviews.
