I would definitely suggest it! I have been every year for 7 years and would not miss it! I have done it twice per trip the past few years! You get to experience the extra special Christmas Disney things on the party nights. Snow on mainstreet, hot cocoa and cookies, special fireworks, less wait time, characters in christmas costumes with less wait, special christmas parade, free picture, free button, ability to purchase MVMCP items exclusive to party goers, and less wait on the rides. I will agree the shows are crowded but I did not find them any more crowded than normal. If you go on tuesday or thursday night then the crowds are minimal and it seems you are almost in the park alone. Keep in mind I would suggest you love Christmas to pay the extra money. But, the past poster is right....you can get in at 4pm and can stay til 1am for less than $50 which is less than a one day ticket, plus you get less crowds and the extras! We are going Dec 15th and the 19th this year! YEAH! Hope you have fun!
