Rehearsal dinner might work!
I dont know what mood i'll be in having had to pack for honeymoon that day cuz we are leaving bright and early for hawaii on the 14th and our flight leaves from Cincinatti which is an hour north of here too. so no time to last minute pack because the nigth before we'll be busy.
I like this idea though. I'll email the four of them and see how they feel about it.
