CSR is a really nice resort. It feels less frenzied than other Disney resorts. Probably because the place is big, and because the theming is toned down (and part of it is used for conventions). There are still some things for the kids (the pool opening ceremony is cute) and there are plenty of kids around, but not as many little ones as you will see at many resorts.
The hot tub is really nice and huge, and secluded a bit. The grounds are beautiful, the pepper market is okay, and the outside bar makes some decent drinks.
Walking from the front desk to one of the back buildings is a long walk if your feet (or you!) are tired. It isn't a big deal if you are just going to your room, because the buses circle the resort and no particular room is horribly far from a bus stop to the parks. However, walking up to have dinner or just get a coffee is a drag if you're beat.
The rooms are really comfortable and peaceful and the resort is very quiet because of the way it is spread out.
