A.O.
i had about that many at my son's as well. i opted to rent out the field house at my local park district and had the event catered. luckily the park district i used was very clean, very organized, and sat on beautiful grounds with a lake and a huge open place to run around as well as a playground. i was so worried about how to entertain all the kids that would be there and had so many games prepared but kids find ways to entertain themselves. we only ended up playing one party game. definitely best to start planning now, it took alot of work! good luck and happy early bday to your little guy.
