If I buy a MYW 6 day ticket with no park hopping or water parks can I use one of the 6 days to visit a water park instead of one of the main theme parks. I know it prob seems a waste of money but I can get a 3 day base ticket plus 3 days free for a good price and as we are going in Dec we don't know if we wld even visit the waterparks. However we only need 5 disney days so was hoping I cld use the extra day for a waterpark if hot or Disneyquest if raining. Wld seem to be in Disneys best financial interest! Anyone ever done this or know the answer?
