help!!!....

I need birthday ideas for Little Prince's SIXTH birthday which is fast approaching - we're down to 24 days!!! And, I have absolutely NO ideas on what to do. There are EIGHTEEN kids in his class, plus another maybe ten kids that he just knows that I must invite, so it needs to be something economical (read: CHEAP) and yet cool enough for six year olds.

Now, the good news is that tonight we went to dinner where they have a balloon artist and Little Prince asked the guy if he could come to his birthday party....so we've got a start, but how much can one guy entertain that many kids?!?! The problem with having the party at my house is I don't have a lot of room outside for the kids to play...I was thinking of doing an "old fashioned" party, with the old standard party games that kids don't play anymore, like pin the tail on the donkey, etc.

So, here's the contest. I want your ideas and in return, you'll win my undying love and adoration! Let's all get those creative juices flowin'.
