Do you need cash (or are cc acceptable form of payment) for rides/attractions?

For the train yes but for walking the whole park it is free

Cards work just as good

you can use credit card to buy tickets for the carousel and train, etc.

Credit and debit cards are accepted.

They do accept cards for the tickets to ride the carousel and the train ride. The other places that do food accept them also.

Credits cards are accepted

They accept cc

You can use credit cards for payment

Cash is king but cc will be ok

CC works.

Both cash and credit cards are accepted.

Cards or cash. You name it!
