I rented one at the bullseye in September because the ones at the main pool were gone already so yes, they do exist.
I can't remember the hours exactly but I think it was 10am check-in until 5 or 6pm maybe? I went to
MNSSHP so we cut out early to get ready.
Here is the
website with info about amenities. It's spot on with a tv, sodas, water, chips, fruit plate, dessert plate. Nice chairs and towels. Best part was the server cause we had some lovely drinks and lunch! They can confirm hours with you if you call.
Cost was $318 on Labor Day.
10/10 recommend - not having sunburn was the best decision ever.
