What should I do about water? Can you bring it into the park? If not, are there vending machines or water bottles? What is the cheapest way?

Best ways to bring you home water is expensive there but if you drink sodas and stuff you can get in souvenir cup and drink all day

The cheapest way is the souvenir cup for almost $15 because you have unlimited refills

Water yes any thing else no . No food or drink vut the refill cup

Cheapest way is to bring your own.

I brought a bottle of water to the park with no problem. The cheapest way to go might be to buy the Drink All Day voucher that comes with a souvenir cup for about $15. You can then refill the cup basically every ten minutes or so.

Yes there vending

I think you're allowed one water bottle but there are vending machines everywhere and restaurants
