The only one I know about that does a special NYE celebration is the GF. However, if you want, on NYE go to the bridge b/t BC and BWI and watch the EPCOT fireworks or go just inside International Gateway at EPCOT and watch the fireworks. That's what we did when we were staying at the BCV during NYE and it wasn't that bad. And you're right, the parks are wall to wall. We have tried MK and EPCOT on NYE and it's bad no matter where you go.
