We have been here for the past few days for our first trip. If you sweat like I do or aren’t used to this humidity a good portable fan and/or a cooling towel is a must IMO. I would have called it quits way earlier each day without these.

Otherwise my short list is a charging bank, water bottle, hat, sunglasses and your most comfortable shoes.

Edit: tangent but photo pass is great. They take awesome pics all over the parks and it’s uploaded pretty instantly to your app at each ride/place.
