I am taking an eight night trip to Disney/Universal split as 5 nights at Disney (AKL) and 3 nights at Universal (RP) at the end of August. Our group is two adults and four kids (3 ten year olds and 1 seven year old). I haven't bought our tickets yet because I can't decide on whether or not we should do any of the water parks or both of them. We have never been to either before but with the August heat I thought it might be a nice change. The biggest draw for the Universal part of the trip is Harry Potter so I want to make sure I have enough time for that but I hear Volcano Bay is very good so I am tempted to check that out. My kiddos and their friends are all pool people so I know they will enjoy the pools or the waterparks. Any thoughts or recommendations would be very much appreciated. I don't want to overplan the trip so much that we are all totally exhausted. Are the water parks relaxing or just as busy as the regular parks?
