I've stayed at both. I've returned to one: Coronado. I do love that CBR is easy to get to parks DHS and EPCOT, and the feel is excellent here. But Coronado seems to have an extra amount of magic to it. We love the Rancho area. Quiet and close to the pool.
Pepper Market has lots of good options - especially for a counter service. Both are really good on bus stops as I recall. Not sure if that's still the case. It's been a while. If I could, I'd return to Coronado. But with a family of 5, we only fit at POR or CBR now.
