We stayed in 2107, which is Concierge Class on the 12th floor. This was an awesome room with a balcony, and the balcony is bigger than other ones too. Awesome floor to be on since that is the same level is the pool and one floor up is Oceanview Buffet which has breakfast/lunch. Great location. We will always get a balcony from now on and will probably check out Aqua Class too. They got to it in Blu, which I heard was amazing. If you can afford a balcony, it is worth every penny.
The room was laid out very well and was pretty spacious. Very quiet too.
