I think you need to decide what you will utilize the most at the resort. For us, we have younger kids and will be doing naps and rest time in the afternoon so we want to be close to the dig site and a bus stop. I requested Cabanas but will also like the Ranchos section right by the Dig site, closest to Cabanas. I think Casitas looks the prettiest and is close to the restaurants, lounge etc.. but far from the themed pool. I also heard if there is a convention going on, they try and keep them all in Casitas. Some of the Ranchos buildings, seem far from everything - so if you want peace and quiet, they would be perfect.
