Can people still spend the night here? If so, do you know how much?

You can. I'm wanting to say it's around $50-100 for the whole night.

Yes you can spend the night. For a public night it's $75 per person and there's a max of 40 people. Or you can pay $1200 for a private night with up to 20 people if you just want to go with people that you know.

Jamie you are right. I think it's closer to the 100
