We spent the day at Disney’s Typhoon Lagoon and it was a blast! It has something for everyone of any age. We opted for the after 2pm passes which was just right for us since it let us splash and play for a few hours in the hot part of the day without the crowds that are there in the morning.
A great addition is that there are photopass opportunities even at the waterpark. We got to meet Lilo and get a picture of our family as we came splashing down on the group raft ride.
I would highly recommend a trip to the water park along with your Disney vacation.
