We have stayed in all views. They are all wonderful! The Downtown Disney view is fun. At night, you can see all that is going on with people, lights and the musicians. When you close your sliding glass door you don't hear a thing (this is the case for all rooms). The Grizzley View is of DCA where Grizzley Run and Soarin is. It just depends on where and how high you are as to what you see. You can also see the monorail go by. The pool view is just that as well as seeing Paradise Pier. There is also the Paradise Pier view. There is a grass area below and the Paradise Pier with all the lights at night. It's really pretty. The court yard is pretty with all the trees and the monorail goes through there as well. I guess it's also how much you want to spend. Each view is a different price.
We spend 5 days and this tends to be good. We can take our time see the parks, going on rides and make reservations at different restaurants each day and take a tour. It just depends on what you want to do. Sounds like you are in for a wonderful trip!!!
