Meredith, you've already received so many wonderful suggestions but I would second the ladies motions to do a really nice dinner for those close to you that didn't make it to RM. I think it would be really intimate and you all could experience ambiance at a nice restaurant that maybe quite a few of you have wanted to check out. Possibly you could do something like small plates and rent out the room of that nice restaurant you mentioned from like 2pm - 6pm and that way people wouldn't be expecting a full meal. I don't know how you feel about that but it is just a suggestion. My family might not go for it and would want to eat ( ;-) ), but I've attended something done tastefully and in a classy manner that was similar. Just don't stress yourself out, whatever you do!!!
And Amanda, I have not even began dress shopping yet, but that price for alterations seems awfully high! I hope you can find something alot cheaper!
That was actually a thought because the restaurant I mentioned actually specializes in tasting plates and they're really good. So, I'm definitely going to keep that in mind. Thanks for the suggestion!
