I decided on a Grizzly Peak view for all of the reasons FastPass said. We like to take breaks during the afternoon, and wanted to be as close to the park as possible. I thought we had the absolute perfect room. It was on the 5th floor, directly over the GCH entrance to DCA. It was close to the elevator that FastPass mentioned, but not so close that you could hear it. It took us around one minute to get from the exit of Grizzly River Run up to our room to dry off. The nighttime view was nice, with Tower of Terror in the background; we could even see the fireworks off to the side, but we were seldom in our room at night, except to sleep.
If you spend more time in your room at night, or if you are going during the winter when park hours and daylight hours are shorter, a Paradise Pier view might be desireable. But still, I loved being right next to Grizzly River Run.
I had my agent put a Grizzly Peak request on my reservation. Then, following advice I read on these boards, I called the hotel 2 days before my arrival and requested a Grizzly Peak view, 3rd floor or higher. The cast member taking the request was very friendly. Again, I don't think I could have gotten a better non-suite room.
