My boyfriend and I have each been on four cruises...one with Carnival, one on RCI's Adventure of the Seas, one on Freedom of the Seas, and this most recent one on Serenade of the Seas. This was my least favorite of the four.
The pros:
Most of the staff were wonderful. Our waiter, Maya, was THE BEST!!! She was very friendly and seemed to truly want our dining experience to be top-notch. And the assitant waiter, Ramon, was very attentive. Our room steward, Marta, was great, and most of the staff we met was helpful and friendly.
We were in 7026, and it was above the Tropical Theatre. We could hear the music from the shows in our room, however the shows typically end fairly early, so it wasn't much of a problem. The balcony was bigger than the one we had on Adventure of the Seas, and that was a pleasant surprise to us. The rest of the room was pretty typical...not much room around the bed; small closet and small bathroom.
