We've stayed at both, and love both, but they are different. CSR is a very large, spread out resort. To me it's very remote & very relaxing, which is great after a long day at a park. Swan/Dolphin on the other hand is right in the middle of all the Epcot Resorts, the Boardwalk, and right by Epcot & MGM. It has a much busier atmosphere than CSR. However I LOVE the convenience of never having to take a bus/car to Epcot or MGM, it's right there! I say definitely try the Dolphin if you've gone to CSR before.
