How much is it to rent a space? Are all spaces the same? Do you get to choose your spot? How do you get a hold of someone to rent one?

I would just go there and check

Ive been calling for two days, no answer.

I went there once, they have several different setups, people weren't around till about Thursday for renting spaces.

Yes, give them a call...

Call them

Call Thursday or Friday in the morning to reserve a spot. Don't walk up and take a spot. They may already be taken.

Lena's right, it's more of a walk up and ask sort of place.
