Yes, they definitely rent chairs. On credit cards, jeez, I don't know. One thing to consider--Club O rents chairs, but if you are facing the water, immediately to the left of the Club O chairs, another vendor also has chairs that you can use while clothing optional. The Club O chairs are orange strap chairs, not that comfortable. The vendor immediately to their left, facing the water, has PADDED chairs, and they also have a small table in between the chairs. I think the price is exactly the same as the Club O chairs--$20 for two chairs and an umbrella, and in the case of the other vendor, a small table, which I love having that. It's not a far walk from the other chairs to the Perch, as the Perch is on the end of the beach closest to the other chairs.
