We were in the Tahiti...this is the building closest to the walkway to the T&TC which was very convenient for going to MK by ferry/monorail. The building was a long walk from volcano pool & main building, but we preferred being so close to the T & TC.
As for the view, we were on the 3rd floor, facing the MK...we had a fabulous view of Wishes every night, and of the Electric Boat parade. And every morning, we started our day with a cup of coffee on the deck with a view of the castle...lovely.
I will say that if you're on the 2nd floor or the first floor facing the MK lagoon your view could very well be blocked by the lush vegetation...even some of the 3rd floor rooms were probably blocked at least partially by very tall palm trees. So I suppose you could be wasting your money if you pay for a MK view & get a vegetation view with a little water showing through!
