Tube rental is $7 a tube. The location is before you enter the park. Can't miss it because you have to drive right by it. There are picnic tables and grills scattered everywhere in the parking lot area before you hit the spring. You are allowed to grill or cook but you are not allowed to do it down there this spring. There is also a concession stand located in a huge building with public restrooms. The concession stand sells drinks snacks burgers and other items. There is no other charge other than the charge of admission at the gate. When I went I only paid the $5 for me and my kids to enter at the gate. We had our own tubes. And we brought our own lunches. It was a great inexpensive day.
Just went on 3/28/18. Tubes are $7 a piece. They sell the tubes outside of the park. Yes your allowed to cookout. $5 admission, is what they charged me for 4 people.
Intertubes prices fluctuate. Yes you are allowed. They have a quick meal and snack store. Other than that, they do offer reserved cabins.
