I agree. This is actually the only thing we spring extra for, other than water parks and more (because we spend days at the water parks and dQ) and we dont even consider not going!
Much of the fun is in the preparation for us…last year we all dressed as pirates, and we bought all our stuff on Ebay…the year before we were all different random Disney characters…even NOT dressing up too much is fun.
The special treatment you get on this night, the light crowds, the awesome fireworks show, the parade and the CANDY - it is just awesome.
I recommend not going to a park during the day that day, just taking it easy at the pool, and have a NAP. Have dinner either onsite or at a monorail resort EARLY! You can get into the park by 4:00 with your party ticket, but the party does not start until 7:00…it really is a full day - park closes at midnight and we have been known to be some of the last ones out…
