Solstice class. A1/A2 amenities are the same. Some prefer fwd A2 cabins due to gym proximity, Persian Gardens and relaxation room. Fwd starboard A2 cabins on Deck 11 (i.e. 1520) offer direct gym access as there is a "secret stairwell" leading to Deck 12. Many fwd A2 cabins look down directly to the water and get more sunlight due to no overhang.
A1 cabins are closer to midship. Some A1s have large balconies, i.e Deck 11, #1605.
Avoid Deck 11 cabins with parked window washing equipment obstructions, i.e. #1552, 1554.
