When my DW and I stayed at the GCH last Aug. We had a standard view which was very nice view. If you are looking at the entrance to hotel, we were just about all the way to the right, top floor. From our balcony we had a nice view of DLH. Looking a little to our left, a nice view of PPH. If we turned 90 degrees to our left we could see some of the rides at the PP section of DCA. To our right were views of the DTD leading to DLH. Needless to say, not a bad view at all.
Also, if you do stay, take the tour of the hotel they offer in the afternoons. It is about an hour long and it is a neat tour. The CM explains the theming of the Hotel as well as the Arts and Crafts movement and some of the pieces of art in the Hotel.
Regardless of what view you choose it is an amazing Hotel.
