Be sure to specify WHICH view you want, i.e. EPCOT view, East side of hotel. We asked for park view to watch fireworks, and got a not-so-great "view" of MGM and the west side of Crescent Lake. Since there was little to look at, we really didn't use the balcony at all.
The Swan is great, however. The boats to EPCOT and MGM were a nice feature, though on the EE day at MGM, the first two boats arrived full, and didn't take any S/D people, so we ended up walking and getting there when the park opened to the public. Boo.
