Sailed on the Adventure of the Seas, out of San Juan.
Checking in at San Juan was easy, even though there were a lot of people there and in line, we (my wife & I) were through it all and on the ship in 15-20 minutes.
We had a balcony room. Room was clean, on 7th deck. Bathroom wasn't real big, but enough room and everything was clean and worked fine. We had our bed set up as a king bed, also had a sofa in our room. Closet, desk, with TV and fridge, plenty of room for the 2 of us. We were mid-ship, 7th floor was quiet, not too far from anything. The dining room for us was on 4th floor, the Windjammer buffet dining room was on deck 11, and Royal Prominaide was on deck 5. We walked the Prominaide every day/evening, and often stopped at the cafe/starbucks to get drinks or a snack, was included with our beverage package. Even ate a light breakfast there one morning, but they didn't have much out for breakfast. They almost always had small sandwiches and pizza by the slice.
Cabin with a balcony is the only way to go!
