Are you allowed plastic water Bottles? If not,is there a place to buy water?

No you can’t have water bottles and you can buy them

You can not bring in outside food or drinks. They have a concession but it is Pricy. I suggest leaving an ice chest in your car if you are going for a long time (cost of lunch adds up) because they will let you in and out if you get a stamp.

No

Agreed. No outside food or drink.

You cannot bring in water bottles, but they do have a water fountain.
