Are you allowed to bring a guest? If so, how often can they bring a guest? Is there a guest fee? How much is the fee?

Yes, not much, yes & too much!

You can bring a guest, but they'll try to sell them a membership. It's probably best to call and let them know you'd like to bring a guest. I dont believe there's a guest fee. But it's been a long time since I've brought one.

You can get guest privileges on your membership for an extra fee or pay 5 bucks for your guest each time you go.
