hopper ticket + water park
I'm planning to take my 18 yr old sister, 14yrs, 13yrs old cousins to WDW on August for 5n6d.
Decided to go for Animal Lodge with Bunk beds.
My question is if I should get the hopper ticket + water park or not.
My current plan is
Day 1 evening: Arrive and relax
Day 2: one of the parks
Day 3: same
Day 4: same
Day 5: Water Park
Day 6: Animal Park and catch the evening flight home.
If this is my plan, Shouls I get the hopper ticket + water park? If I don't get this deal, where can I get the water park ticket and how much is it?
