"Deluxe" and "Location, location, location!"
I agree with the above posters. We stayed at POR in Nov. 2002 and then Dolphin June 2003. While we enjoyed our stay at POR, if I could get the Dolphin for the same price I would go for it. It is so nice to be able to walk to 2 parks (we walked to both MGM and EPCOT). It is in the middle of everything. The Dolphin pool is great! (But the POR main pool was closed when we were there, so can't compare. We had to use the quiet pool at POR.)
At POR it seemed like just a hotel room. The grounds were beautiful, but it was REALLY cold when we were there (like Winter coat and glove weather) so we didn't spend a lot of time exploring. When we went to the Dolphin, it seemed like a Deluxe, magical vacation!!
We didn't miss the Mickey soap (love the Oatmeal soap at the Dolphin) or the Mickey wake up call. Plus, we had travelers checks to spend, so we wouldn't have charged to the room card anyway.
If you can get it for a comparable price, go for the Dolphin. But I am cheap, so if you can get a good code for POR to make it significantly cheaper (we paid $79/night with AP discount), then POR is great too.
