I have a Hotel (Cabana Bay) question.

I was reading on TripAdvisor comments about the lazy river that’s located in the Cabana Bay hotel. Apparently, please correct me if I am wrong, patrons have to purchase the tubes/rafts to use in the lazy river?

My question is, someone said you can bring your own floats from home? Is this true? Can it be any float or is there a specific type?

Thank you.
