Cabin 6604 · Harmony of the Seas

Cabin 6604 is an Ocean View with Large Balcony (category B) on Harmony of the Seas, 195 square feet plus a private balcony of 39 square feet.

Cabin 6604 is an Ocean View with Large Balcony on Deck 6 of Harmony of the Seas. You are midship. That is about as close to the ship's pivot point as you can get, and in a swell you will feel it less here than anywhere else on board. We score it 9 out of 10 for steadiness, which puts it among the calmest rooms on the ship.

On the ship's plan Sorrento's is on the deck below, about 6 cabins 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 comes out at 6 out of 10, roughly par for this ship. For getting about, 8 out of 10.

Counting from the bow, it is the 82nd cabin position of 205 along Deck 6. You are about as central as the corridor gets, so it is a similar walk whichever way you turn out of your door.

An Ocean View with Large Balcony gives you 195 square feet. The balcony adds another 39 on top of that. A balcony buys you outside space of your own and, on sea days, somewhere to sit that is not the pool deck. It is the step up most people make, and the one they find hardest to give up again.

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 as steady in a swell as any cabin on the ship. 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.
