Do they have ride Lockers at Vulcano Bay?

Individual rides have open spaces you can place your slipper and towels in. Lockers are all paid and come in small, regular and large sizes. Large one costs 16 USD

they have lockers but not individual ride ones..they are 16.00 and there are a few stations around the park

Yesss

Yes, they have. But you have to pay for it.
