Although not an expert when it comes to CS, I have stayed in both Cabanas 9b and Casitas (near bus stop #2). Both were fine, but Ranchos is pretty remote to everything except the main pool. It depends on your priorities. Casitas is actually closer to the Pepper Market, but a little further to the main pool (and visa versa for Cabanas). Both areas offer a quiet pool if all you want is a quick dip and not the fantastic water slide at the main pool.
The biggest impact to our group was the placement of the bus stops. Bus stop #1, which serves Cabanas 9b is an easy walk and offers a lot of shaded area to sit and wait. The other bus stops involve a hike across hot parking lots to smaller bus shelters. Oddly enough, when dropping off, the bus often by-passed bus stop #1 and stopped there last.
Enjoy your stay :wave:
