Boardwalk view rooms at Boardwalk, especially higher floors and the ones down at the Swan/Dolphin end of the Boardwalk, have very nice views of most of the fireworks and some lasers - but you won't see the bay-based water and projections. You can also walk from any of the Epcot-resort-area resorts up to the International Gateway, and see much of the show right before the turnstyles without actually entering the park - if you don't have park tickets that day...if you do have park tickets, the International Gateway drops you right onto the World Showcase Lagoon to see the whole show and then exit quickly without dealing with the mass crowds headed to Epcot's main entrance.
