I second the above poster about just relaxing after the fireworks. This past September, we watched IllumiNations from the pavillion right in front of Italy (Awesome location, by the way...) When the fireworks ended, everyone bolted for the front of Epcot, but we just sat there. They started playing the music from the Millenium CD (my favorite), so we hung around while the crowds thinnned out. It doesn't take long to clear out, so we just sort of strolled slowly through WS listening to the music. I have the greatest pics of my kids dancing to the music with almost no one around! By the time you make it to the front of the park, most of the hoarde will have departed already!
Where will you be staying?? Because the International Gateway may also be an option for you.
