VIP area is pre reserved, so Yes. We got the floating space for 10 people and was so fun ($250). And is better reserve all activities you want to do. All costs are low. Kayaks $10 all day. Floating slides ($10) an hour just for groups.
That is totally up to you. They have a limit and once they're at capacity, you're not allowed in. And for as big as the place is, there is very limited parking.
