I think the only thing that truely disapointed me is the castle at DL. It's just so...underwelming.
That said, DL is a wonderful park. I wouldn't go so far as to say it's better than Magic Kingdom, but it is just as good, with some aspects being much better. Fantasyland is much better designed, from a themeing stand-point, than MK for example.
DCA is, well, it's not bad, but it's not Disney's best effort, either. It needs more attractions, for sure. The rides they do have are quite good though.
I didn't get that "resort" feel from DLR, it's just too small and in the middle of a very well developed area. But it's still a fantastic time. Being from Chicago, my air fare is about the same to CA as it is to FL, so DLR is a great option for us when we need a Disney fix but are short on cash. We got a hotel on Harbor Blvd for $59 a night, the park tickets are MUCH cheaper, and since we don't need to stay as long, that cuts down on meals (and the hotel bill even further). I figure the same trip to WDW would run us at least double.
