Parking. The rest is up to you. Yes drink are to much.
From my experience most venders also do credit card transactions. But cash is king :)
I spent $4 to park, wandered around a couple hours and didn't spend any money. I don't think the food prices are inflated. I haven't paid a lot of attention to the rides, but they look reasonably comparative to carnivals (and in better repair) Vendors carry all sorts if things and some shop keepers are open to price negotiation (collectibles/personal creations).
