If I arrive on a motorcycle how can I access audio without Bluetooth ?

they have audio radio boxes you can borrow for $2 each I believe.

all you need is an FM receiver

Depending on where you are are they play the audio my The concession stand if you dont want to use a radio

They have radios that you rent. But I don't know how much it is.

You can borrow radio for $2

The radio station they use is good if you want to bring your own, or they have tons of portable radios you can rent for $2.00 and they do have a great sound quality. You will have to leave your driver's license with them as collateral. Pick them up at the entry pay window when you get there or you can ask for it at the beginning of the concession stand at any time. (You can also skip the concession stand line by walking up to the entry pay window.)
