We have only stayed at one moderate--the CSR. We love it so much that we will be spending our 25th wedding anniversary trip there (and DH offered me Poly...but I chose CSR). It is large and spread out like the CBR, but they do have a great counter service restaurant (Pepper Market) where you can get a steak on the dining plan and a sit-down restaurant (Maya Grill). Although a convention hotel, we have never had any issues with the conventioneers--half the time we don't even know they are there, and when we do see them, they are headed to their meetings. Pepper Market may be a little crowded at peak lunch times, but we have never had a problem at the pool and have often had the pool to ourselves with a few families, and my DH and I have spent hours in the hot tub with no other people around. There are the quiet pools in each section, the Dig Site with slide, volleyball court and the hot tub; the landscaping is lovely and the resort is beautiful at night when the sun has gone down and the lights are on at the resort, especially in the Casitas section among all the buildings with the fountains and plants/flowers. They also have a fitness center and spa (which I use every trip for a massage). They have also recently added the Rix--a lounge that has live entertainment on certain nights. I am sure whichever you choose you will have a lovely time.
