We have been to wdw for 2 NYE's. First thing we decided was to avoid MK. It is usually closed to all guests(including resort guests) by 10am. If you do decide to go there, plan on getting there early and staying! You should not try to park hop because you will not be readmitted if they are at max capacity..even if you have ADR. 2003-4 we started at MGM and then went to epcot around 4:30pm. It was fine at MGM and we toured well with FP. Epcot was crazy crowded, but fun. They gave out hats and noise makers around 6pm and we had PS at Teppanyaki for 7:30pm. There were outdoor music venues and then it started to rain..pour. But it was fun. 2004-5, We started and stayed at MGM. They had live bands and radio disney inpm. We had PS at Brown Derby and then did Fantasmic. Around 11:30pm we took boat back to Swan and watched Fireworks at MGM (Fantasy in the Sky) from our room on 11 th floor. Then we saw some on Epcot fireworks from the dock at swan/dolphin. It was nice being back at resort before the corwds and still have a chance to see the great fireworks. I think you can still plan to park hop to Epcot as it is such a big park. If you want MK..make sure to make your ADR's asap.
Have fun
