Do they take debit cards? Like the food places and stuff or do you need cash?

Most, if not all do. However, I'd still bring cash in case the card reader is broken, and so that you don't have to pay atm fees.

They take cards.

Yes

Yes they do take plastics

All the vendors take plastic. Atm's are available as well ma'am

All take credit cards. But i wouldnt advise going to such a entertaining place such as this without cash on hand as a backup

Yes, they do. I can't speak for every vendor in the park but I haven't ran into a cash only place yet.
