We usually have a local magician come in and mingle with the guests showing them tricks as he goes. That is a big hit every year. One year we had a male stripper come in for a few minutes after the ladies had had a few too many. Got some great, funny photos. Nothing real bawdy or out of hand. One year we had an Elvis impersonator come in for about 30 minutes during the middle of the party and do a set. That was a lot of fun. Ordinarily we have around 60 to 100 guests depending on whose team is playing football where that week. The party lasts from around 7:00 p.m. to around 3:00 a.m. We intermingle party music with karaoke. We've never had a problem with the party slowing down for some reason, although I worry about that a bit every year. People seem to entertain themselves pretty well if they have enough food, drink, novel decorations and good company. We've never done any party games per se but would like to. Just haven't come up with anything manageable involving that number of people. So I'm eavesdropping on your thread in hopes of coming up with something. Good luck!
