Cabin 3640 · Quantum of the Seas
Deck 3 · Royal Caribbean International
Cabin 3640 is an Ocean View (category N) on Quantum of the Seas, 126 square feet.
Cabin 3640 is an Ocean View on Deck 3 of Quantum 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. You are near the middle of the hull, where the ship does the least moving. In rough water that matters more than most people expect. We score it 9 out of 10 for steadiness, which puts it among the calmest rooms on the ship.
It is 4 cabins along the corridor to the aft lift bank, starboard. Close enough to be useful, far enough that it should not keep you awake. Quantum runs four lift banks on most decks, a port and starboard pair forward and another pair aft, with two on deck 16. Conventional lifts with call buttons in the lobby and deck buttons in the car. Worth knowing: the cars are quiet, the lobby is not. A cabin beside one hears doors, waiting conversation and footfall in the corridor, heaviest when a show lets out and after the late dinner seating. Quiet scores 5 out of 10. There is enough going on nearby that a light sleeper should think about it. For getting about, 8 out of 10.
Counting from the bow, it is the 47th cabin position of 53 along Deck 3. Deck 3 also has Music Hall, Royal Theatre, Casino Royale and Chic on it. There are 106 cabins along this deck, so the corridor is short and rarely busy.
An Ocean View gives you 126 square feet. You get daylight and a sense of where you are without paying balcony money. The window does not open, so it is the view but not the air.
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 2,099 cabins on board, as steady in a swell as any cabin on the ship and better placed for getting around than 89 per cent of them. 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.
