This year we did Charlie's birthday at Chuck E. Cheese. That is the bad news. The good news is that we did it on Super Bowl Sunday, so there was really no one else there, and it was pretty painless, (as far as Chuck E. Cheese goes).
This was the only hitch in the whole day. Part of the party package was that Charlie got to stand in the ticket booth and grab as many tickets as he could. However, it wasn't really explained to him what would happen and he completely freaked out. We are adding the experience to the list that he will be talking to his future therapist about.
