While we have never stayed at the CSR, we have stayed at the CBR six years in a row and already have our 7th stay booked for 2012. I believe the theming of the CBR would appeal to your kids'.
The standard and preferred (additional charge) rooms have a slight Nemo theme and then there are over-the-top pirate themed rooms (an additional charge). In addition to the main pool and a separate kids' water play area, there are quiet pools in each of the resort villages making it very convenient for families. If your kids want to burn off some energy, you could take them to the playground on the island or let them play on the smaller playgrounds that are on a few of the beaches.
During each of our stays, we have had excellent bus service. There are covered bus stops in each of the villages and, even though the buses stop at each one, it won't take long before you are out of the resort and on your way to the parks. Because the resort is centrally located, it won't take you long to get to any Disney destination.
The food court has a nice variety of foods to choose from. At the burger station, the kids can get a meal in a plastic sand pail that they get to keep.
Every year, we think "maybe we'll try something new" and look at the other resorts. Then, we get to thinking about how much we like the CBR and we book another stay there. It has such a laid back feel to it that it's a nice place to relax after spending a long day in the parks.
