How old do you have to be to rent a tube?

You need a driver's license for a maximum of 5 tube rentals. Cash is accepted and no need for a credit card

It's not a credit card you have to have, they require at least 1 person per group who is paying to give them ur driver's license to hold, then when u return the tubes u get it back.

You have to have a credit card to rent a tube, so at least 18yo. But you can be 8yo or older to use a tube, but they have to be at least 4' tall.
