Short answer
A guarantee cabin, sometimes shown as GTY, is a booking where you choose a cabin category, such as interior, ocean view, balcony or suite, and the cruise line chooses the specific room and deck later. You are guaranteed a cabin in the category you paid for, or in some cases a higher one. It can lower your fare, but you give up control over location. It is a good fit for flexible travelers and a poor fit for those who are sensitive to motion or noise, or who need a specific room.
How a guarantee cabin works
When you book a normal cabin, you pick a specific room number from the available cabins. With a guarantee booking, you choose the category only. The cruise line assigns your room later, as it sorts out its remaining cabins. Cruise lines use these bookings to manage their inventory and fill the ship.
The promise is about the category. You will not be placed in a lower category than you booked. You may sometimes be placed in a higher one, but that is not promised.
Benefits
- Possible savings. Guarantee fares are often lower than choosing your own cabin. The discount varies: sometimes it is small, sometimes there is none, and some lines price the two the same. Compare the numbers each time.
- Possible upgrade. If the cruise line needs space in your category, it may move you into a better one at no extra cost. This is not something to count on.
- Availability. When a sailing is nearly full, a guarantee booking may be the only way to get on board.
Drawbacks
- No say over location. You can’t pick the deck or position, and the room you receive may be near noisy venues such as a pool deck, nightclub or galley, or close to the bow or stern. See the best cabin location to avoid motion.
- Leftover cabins. Guarantee rooms are often drawn from what is left after other guests pick their rooms. That can mean less desirable spots, although it depends on the ship and sailing.
- Possible obstructed views. If you book an ocean view or balcony category, the room may have a partly blocked view.
- Late assignment. You may not know your cabin number until closer to the sailing, or in some cases the day of boarding.
- Groups. If you book several guarantee cabins, the cruise line may not put them close together.
- Promotion limits. Some lines or promotions exclude guarantee bookings from certain perks. Read the terms.
- Accessibility and special needs. If you need an accessible room or a specific layout, don’t rely on a guarantee booking without talking to the cruise line.
When are guarantee cabins assigned?
There isn’t a single rule. Assignments can come months, weeks or days ahead, and sometimes at embarkation. Many guests report receiving their room a few weeks before sailing. Check your booking and your cruise line’s app or website, and confirm the cabin number again before you travel because it can change, for instance if you are upgraded.
Will you get an upgrade?
You might, but you can’t predict it. An upgrade depends on how full the ship is and which categories are in demand. The only promise is a cabin in your category or better. Don’t book a guarantee cabin counting on a free upgrade.
Who should book one, and who should skip
May be a good fit if you:
- Are on a tight budget
- Don’t mind where in the ship you sleep
- Plan to spend little time in the cabin
- Are booking an interior category, where view and window obstructions are not an issue. See inside versus balcony cabins
- Are a solo traveler who is flexible
May want to skip if you:
- Are prone to motion sickness and want a midship, lower-deck room
- Need to be near elevators, or have mobility issues
- Are traveling with small children, or need an accessible cabin
- Want a specific view, such as a balcony facing aft
- Are booking several rooms for a group who must be together
- Are a light sleeper concerned about noise
Check before booking
- Compare prices. Look at the price of a guarantee cabin against picking a specific room in the same category. If they match, choose your own room.
- Read the terms. Look at what the fare includes and what promotions apply.
- Look at the deck plan to see which kinds of cabin might be left over.
- Ask your travel agent whether the line allows you to select a room later, possibly for a fee.
- Check the change terms. See changing your cruise after booking Carnival for how changes are generally handled.
- Consider timing. Our guide to the best time to book a cruise and finding unsold cabins explain how guarantee fares fit into cruise pricing.
After you are assigned
- Look up the cabin on the deck plan, and check what’s above and below.
- If the location doesn’t suit you, call the cruise line or your travel agent. Changes may or may not be possible, and may cost more.
- Keep your confirmation, and double check the number at check-in.
