I too am just back and really liked the Dolphin overall and would stay there again. However had a disappointment at check in. Had reserved a king bed room many months ago. Was told at check in we had a room with a lovely view of Epcot and a king bed... well we had a nice view but no king bed. I hauled all the way back to the desk (it was near midnight as our plane was delayed) and I was told no king bed rooms were available. There was some discussion about what had happened with the other receptionist and then I decided to walk away and accept what it was. I didn't want this to ruin my trip but it was disappointing as this was our first ever trip without our kids and the king bed would have been nicer.
Our room was at the end of the hall, east wing and faced YC and part of the lake and full view of Spaceship Earth. The room was sort of L shaped and if you looked left you could see a bit of the infamous dumpster view but certainly not much and I just didn't look that way.
Only went to the pool one afternoon, it was very nice but crowded. We found chairs on the beach and enjoyed it very much.
Ate at Ill Mulino in Swan, very busy but were seated directly. Our service and food was very good but didn't really like the atmosphere, it was super noisy. Got grab and go from Picabu but ate else where for the other nights.
There was a wedding reception one evening and a convention rolled in half way through but that didn't bother us too much. It is a nice place and I would stay again. However would not do Easter week again, only went to see DS's marching band. It was such a crowded week!
