Is staying overnight at a museum possible?

Hello! I was wondering if there are any museums here that offer overnight stays for adults? My boyfriend has always wanted to do this and he was robbed of the chance to when he was a kid (it would have been an overnight spy camp at the museum in Philadelphia). I thought it might be a cool surprise for his birthday to take him to a museum overnight, but its hard to find information about it anywhere. When I try looking all I see is stuff for children…

Even if I wanted to talk to a museum and arrange something, I think it would be more fun if activities were planned or something? Idk maybe I could invite some of his/our friends….

Is it possible to organize something like that here? Would it garner any interest? I’ve lived here my whole life but I’ve never tried to do anything like this before. Would love any info available!!
