What should i pack for my 2 day school field trip. Read details.?

The key to a good time is layering. Will you be able to rent a locker there or go back to the bus? Bring a pair of pants. I would avoid sweats because if you get wet it will be like wearing a dirty diaper (eewwww!) It will take a while for it to dry and you will be cold and uncomfortable. Also, if you just have shorts you may get really cold waiting in line in the shade and after the sun sets. Wear comfortable shoes/sneakers. Think twice before wearing flip-flops if that is what you usually wear. They may not be allowed on some rides. I hope the water park is heated. Wear something that dries fast. Don't forget a big towel (unless they told you specifically not to bring one.) Have fun. Be safe. Wear sunscreen.
