In all honesty, you really should not have the party last more than 2 hours (if you want your baby to last). It is so overwhelming. When my kids turned one, we had a big party, but we let the baby dictate what we did. It is too hard to have structure with a one year old in that setting. We only had them open a couple of gifts, if any....not enough interest. I would not spend a zillion dollars on it. If your baby is into a particular object (ie trains) etc...work around that. I know this is a vague response, I am sorry, but the parties actually get more fun as they get older.
