We booked a "spa interior" cabin for a very last minute deal - a huge bargain! (You could also go across the hallway for a spa/balcony if you prefer). I would *highly* recommend it!! We were spoiled and pampered! To say it was an "upgrade" from any other cabin we've stayed in is a major understatement!! The decor was swanky and sophisticated, inside the cabin and out in the hallway. Our room steward was seasoned and highly competent!
We had a private entrance to the spa, which was good, because when we went to and from, we were only in our (provided) bathrobes and slippers! In addition to the bathrobe and slippers, we also had special beach towels that were a different color than most on the ship, and we didn't have to check them out, our room steward just replaced them for us when they were wet.
We also had all the spa products free in our room - the soaps, the shampoo, the conditioner, the lotion, and even a fabreeze-like spray for "aroma-therapy"! We also received a 'couples' spa treatment 2 for the price of 1, which we gladly did on our first day at sea, and 3 free exercise classes (which we never did because they were early in the morning!). The entire spa area is 'adults only' and only a handful of guests have access to the entire area in comparison to the 3,000 people on the ship, so it was always a great way to get away from the crowds and find peace and quiet.
As stated in my review, the spa cabin was HEAVENLY and well worth booking. 1047 specifically was right under the spa office, so when the girls wore heels to walk in, I could hear them 'clickity clacking' above my bed in the morning. I would recommend going closer to the end of the ship if possible, which is also closer to the private spa entrance.
