What You'll Build

Guests should be able to search for available rooms for a specific date range (check-in date to check-out date).
The system should check room availability by detecting overlapping reservations using a date range overlap detection algorithm.
Guests should be able to create reservations for available rooms, which transitions the room from Available to Reserved state.
Guests should be able to cancel their reservations, which releases the room back to Available state.
The system should support check-in process, which transitions the room from Reserved to Occupied state and updates reservation status to Confirmed.
