Can people still come out for the day and go swimming?

Yes

Yes. I believe it's a dollar an adult. And 50 cents a child. $5 cooler fee, of you have alcohol. We always bring a cooler but we don't drink alcohol so it's only with water and kids drinks so he never charges us the $5 for the cooler. He only charges us for the children and us..

Yes but he charges so much a person and so much a cooler

Yep
