Cabin 3840 · Symphony of the Seas

Cabin 3840 is an Interior on Symphony of the Seas, 150 to 172 square feet.

Cabin 3840 is an Interior on Deck 3 of Symphony of the Seas, and it sits midship. You are near the bottom of the passenger decks, which is the steadiest place to be, though it is a fair climb to the open air. This is the steady part of the ship. When it gets lumpy, midship is where you want to be. We score it 10 out of 10 for steadiness, which puts it among the calmest rooms on the ship.

On the ship's plan Casino Royale is on the deck above, about 1 cabin along from you. A deck between you takes most of the noise out of it, and it is a short trip when you want it. Quiet scores 5 out of 10. There is enough going on nearby that a light sleeper should think about it. For getting about it scores 9 out of 10, so almost everything is a short walk.

Counting from the bow, it is the 38th cabin position of 49 along Deck 3. Deck 3 also has Main Dining Room and Conference Center on it. There are 127 cabins along this deck, so the corridor is a fairly ordinary length.

An Interior gives you 150-172 square feet. No window, which makes it the darkest and cheapest room on board and, for a lot of people, the best sleep they get all week. If waking to daylight matters to you, an ocean view is the smallest step up.

On loyalty, this is a standard grade, so Crown and Anchor credits its base one cruise point a night. There are exactly two ways to double that: move up to a suite, or sail on your own on a double occupancy fare. Either pays two a night, and doing both pays three. Checked against the line's own published terms on 8 September 2026.

Against the rest of the ship it is noisier than three quarters of the 2,798 cabins on board, as steady in a swell as any cabin on the ship and as well placed for getting around as any cabin aboard. It suits travellers prone to seasickness and families running back to the cabin several times a day. It is a poor fit for anyone who wakes when a door closes.

Scored by Cruise Ship Wiki using model v1.8, from the position of this cabin relative to every public space on the ship. Each part is out of 10.
