cabin recommendations Celebration outside

[fragilek]

Hi looking for outside cabin recommendations for deck 3 or 4 on the Celebration. I want to make sure it has a double or 2 put together singles and not an L shape layout. I am also looking for a large as possible as I have a wheelchair (it does fold but is still quite bulky as it is a made to measure proper NHS one - not a little travel one). Also can shower seats be requested (have done this on RCL and Carnival)

There are double cabins on deck 3. 539 & 540 are square shaped rather than long and narrow so may be better.

There are also special wheelchair/disabled cabins on deck 7 but don't know which price range they fall into.

Deck plan is towards back of brochure with full details.
