You can book the cabanas at the ticket booth in the park entrance.
They are very expensive for whay you get and have to be reserved online in advance or at thr ticket booth. When we went in sept hardly any of them had been taken. Tried ro get a discount but they wouldny budge on price
As far as I know, we had to check availability for cabanas at the ticket booth. They are usually crazily expensive, but it can be booked at the ticket counter.
