Cabin 12315 · Mardi Gras

Cabin 12315 is an Ocean Suite (category OS1) on Mardi Gras, 275 to 287 square feet plus a private balcony of 46 to 85 square feet. There is a double sofa bed.

Cabin 12315 is an Ocean Suite on Deck 12 of Mardi Gras, and it sits forward of midship. There is some movement here, more than midship and a good deal less than the ends. Most people never think about it. We score it 7 out of 10 for steadiness.

We give it 10 out of 10 for quiet, which is about as peaceful as this ship gets. For getting about it is 3 out of 10, so add a few minutes to everywhere you go.

Of the 225 cabin positions on Deck 12, this is the 77th from forward.

The Ocean Suite grade runs 275-287 square feet. The balcony adds another 46-85 on top of that. At suite level you are buying more than square feet. Suites almost always carry priority boarding and priority disembarkation, and the higher grades on most lines add a restaurant, a lounge or a sun deck of their own. Junior and entry level suites often get none of that, so it is worth checking what this particular grade includes rather than assuming the whole list comes with the word.

A word on loyalty, because the grade misleads people here. Carnival Rewards replaced VIFP on 1 September 2026 and it counts what you spend, not the nights you sail or the room you book, so this suite earns at the same rate per dollar as an interior does. What the grade buys you is the room and the service, not faster status. Checked against the line's own published terms on 8 September 2026.

Against the rest of the ship it is as quiet as anything on board. It suits light sleepers. It is a poor fit for anyone who finds long corridors and stairs hard work.
