group of 5~10 ppl.

I planned to have a birthday party for friend of mine tomorrow. When I called a place, they could not let me use the place because of less than 20 ppl.
I have been Malibu granprix, was fun but not for tomorrow

I am looking for some place where people can have some entertainment such as paintball, kartrace, horse riding, and bbq, etc

anyone knows a place like this?? We can travel 1hr from Atlantic Station, Midtown.
