Holds, requests and booking states

Holds

A hold reserves cabins for a short time before a booking is confirmed:

Kind	For	Default length
Checkout	A guest paying on a channel's website	30 minutes
Option	An agency's option	72 hours
Offer	An alternative date offered on a request	48 hours
Payment	A direct booking waiting for its deposit	24 hours

Holds expire on their own at the exact time: the worker releases them every minute, and nothing depends on someone remembering.

Booking states

State	Meaning	Comes from
Requested	An agency asked; no cabins taken yet	An on-request contract, or an agency over its credit limit
Alternative offered	You proposed another sailing	A request
Waiting for payment (held)	Cabins held until the deposit arrives	A direct (prepaid) booking
Confirmed	Cabins booked	Confirmation, an accepted request, a paid deposit
Paid, cabin unavailable	Money arrived after the hold ran out and the cabins were sold	A late payment, needing a decision

Revisions

Every confirmed change (date, cabins, guests' occupancy) creates a new revision with its price and fee. The history is never overwritten. Each revision also keeps a copy of the policies the booking was sold under.
