Ok, Original post has been changed.
1st, there is NO wedding before the reception/open house/get together (whatever you want to label it). We are having a private ceremony a few weeks before.
2nd, this is a 2nd wedding for both of us and only family & close friends will be there. I expect around 75 at most.
3rd, it's very casual- more of an "open house" situation rather than a traditional reception. I don't expect people to stay all evening but come in & out.
So again, thanks for all your help, ideas & opinions!
