What is a guarantee status on a booking?”
A guarantee means you are guaranteed at least the cabin category it is based on. For example, if you book an inside 4a category guarantee on a Carnival cruise, you will be booked for the cruise and guaranteed that you will have at least an inside stateroom and if you’re real lucky, maybe even an upgrade to an oceanview cabin. The down side is that they can put you anywhere on the ship that is available such as near elevators or lobby areas or even the theatre. Agents like guarantees because there is the wild card chance that they (or you) could get an even better upgrade to a balcony.
