We stayed in the Casitas, building 5, last October and loved it !
Casitas was my first choice , with the Cabanas being second. I guess the theming of the Casitas just appealed to us more.
We were "fairly" close to a bus stop,(#2) but it could have been way worse. It was only a slight problem in the evenings when our feet were tired.
There was a long a long walk to the restaurants and lobby. But that is easily enough solved by hoping a bus that will take you around to bus stop 1 which is in front of the lobby.
Or you could walk around the inner courtyards, which is BEAUTIFUL and enjoy the scenery.
The Pepper Market is eye appealing, but we found the food to be just "okay".
On the other hand, Maya Grill is FABULOUS !!!!
My DH still raves about our meal there, and even though we are trying a new resort this time around, we are planning one of our meals back at the Maya Grill.
I'm certain you will love CSR. The theme pool is wonderful, and the transportation was great as well.Enjoy your trip!
