As you can see from the wdwig link, a lot of the entertainment at the resorts and Pleasure Island is quite expensive. We were there last NYE with 2 teenage boys and so we just enjoyed the parks. Went to MK that morning, but by midmorning left so that we could be sure to get into MGM where we has PS for dinner. We spent the evening at MGM. There was entertainment in all the parks such as bands, DJ's - but no big name entertainment. Still , the entertainment was good. You could buy champagne in the park. They passed out horns and party hats for free and at midnight we saw the most fireworks I have ever seen set off at one time. We have been many times to WDW, so even though the lines for rides were long, it was okay since we had already done everything anyway. Just be ready for a crowd and be sure you have a PS or reservation for supper way ahead of time. Have fun!
