Just a thought...... Depends on the time of the year you go and if you will have a vehicle there....
The first time we went this summer, I packed towels and stored them in a locker for $7 and we didn't even need them. The next time we left everything in the truck and didn't use a locker thinking we would just dry off when we got back to the truck. Still didn't use them. As warm as it is here in the summer, the sun does a great job drying. We just used them to sit on while we drove back to the resort.
