Advise please...We plan on going Dec. 2005 for first use with AP's than plan to go again late August/Sept. 2005. We have #5 people in the family. Planning to stay 7 nights each trip. Is it worth the exta cost to get water parks included in tickets and are there other perks to Preminm pass or better money wise to just stay with AP and do the water park only ones durning stay in Aug/Sept. Can you buy AP's than upgrade to preminm at a good price. Would like to hear your thoughts I have never been there done that AP thing...........
