My little sister's birthday is in December and she has often had the same problem. A couple of years ago my mom had her party at some type of lunar mini golf (in the dark with black lights-REALLY COOL) in the Denton Mall. I don't think it's there anymore, but I think there is one in the Grapevine Mills Mall. Not sure if maybe there is one somewhere closer since I know you said her school friends might not come, but you have time to look! The kids had a blast that year! She's also done one at a pottery place in Denton (again, maybe you can find one closer). All the kids got to pick out a piece of pottery and paint it. Then they left it there for a week to be put in the kiln (sp?) and when they got to get it, it was nice and shiny and they had a really cool keepsake! That's about all I can think of, but I hope this helps!
