I would pick the hotels in this order:
1) Grand Californian (if money was not a problem). The location of the hotel is fantastic. My sister stayed there and their balcony faced DTD. The hotel is actually kind of in the center of DTD. They have a private entrance to CA. The hotel is just beautiful too.
2) DL Hotel
3) Paradise Pier

Of these three, I have only stayed at the PP. That was about 6 years ago. We were not very impressed with it at the time. It just didn't feel very special to us. I think they might have made some changes since then though, so it is probably much better now.
