We have the Poly booked, but I am having troubles in my mind how much more it is cosing us. We will have a 1 and 4 yr old. Only there 2 days, and the one park day is the MK. We will have one full day at the pool. (would love zero entry ) I looked at WL and AKL, and they are not to much less than the Poly. Should i change our reservation?
