Ain't that the truth!!! We always stay at Portofino but last August we had to duck into the HRH lobby because I was feeling faint and dizzy - too much sun!!PBH is my favorite of the three. The rooms are large and the resort is beautiful. It doesn't feel like you are staying at a theme park hotel at all.
I do have to admit though, after a long hot day at the park, I am a bit sad when I have to keep walking past HRH to PBH
