Aqua class on the Summit gives you Blue Dining and free use of the spa (not such a big deal - see my main review) but the cabins themselves are extremely well-layed out with nice verandas. And a good location (Deck 9) directly below the spa and one deck from the buffet and pool.
We booked Aqua class veranda room 9076, starboard side, which was more spacious than I expected. Mirrors through out the ship but especially in state rooms were well placed making everything seem more spacious. Everything was in good repair though there was a bad smell in the bathroom that I found unpleasant (husband did not seem to mind it). There was ample storage space for all of our belongings (4 suitcases plus small bags). From our room we were able to see the islands every morning when we woke with the sunrise which we could not have enjoyed from the port side of the ship.
Our room steward maintained our room to our satisfaction. I liked the toiletries provided and chose to use them over the supplies that I brought. The robes and slippers were a nice touch that I used daily after returning from our ports as I went up to the Persian Gardens and then the pool showers on deck 10. I enjoyed having the extra large shower, extra towels, sauna and hairdryer. There was never anyone else there at the time I would go shower- around 5pm when everyone else was waiting around for sail away.
Don't get a room on the 9th floor. There is noise from the pool bands that goes late into the evening. Also, the balcony has a poor view. The deck from floor 10 extend over the balcony and that inhibits your ability to take pictures coming into ports. There are supports for floor 10 that also block viewing and picture taking.
