I suppose the perfect room at the Dolphin would have a view of the Epcot fireworks and be in the West Wing, close to the pool and elevator. I don't agree that there is a trade-off between view and location. I just think there are fewer of these rooms to be had. We had the standard room and were upgraded to a resort view which was a very nice view of the Boardwalk, cresent lake and the Swan hotel. We had not accumulated any Starwood points, so if we wanted to upgrade to a better view or a balcony, we would have had to pay. The balconies are pretty small, so I didn't mind not having that, and we were never in the room during the fireworks, so not having that view wasn't a problem either. There are three sets of elevators, which run VERY fast, so I didn't mind a short walk to the elevator. We were on the East wing and the West Wing is much closer to the pool.
The one thing I would ask for now is a renovated room. The "old" rooms are nice enough, but those Westin heavenly beds are just that.
