It matters
Just another post about how much etiquette means to our guests. My wedding is May 31 (wow..just 4 days away!). My FI and met with our DJ a couple weeks ago. When he asked what we were serving we said BBQ with beer, wine, champagne, and margaritas (and water, tea, lemonade, and sodas). He then asked if guests would need to pay for their drinks, to which we said "No, we've got that covered." He told us our guests were going to love us, since they will not have to pay for anything. Then, as he was walking us through the reception events, dances, etc, he asked if we would be doing a money dance, when we told him "no, we don't like money dances"...he really seemed to be impressed we would not be asking our guest to pay for drinks or pay us at the wedding.
Re: It matters
I was just talking with a friend who is doing a reading for our wedding about this this past weekend. I mentioned that my mother wanted us to have some sort of wedding favor, but we weren't because we decided we'd rather put that money (and money for some other things we cut out) towards an open bar. Her response: "Yep. People would rather have drinks than candy." At least my people would.
(Please note, my mother also believes we should have an open bar. When I explained that we weren't going to do favors because we wanted to put that money elsewhere, she volunteered to look into to putting together a candy bar for us. I told her to go for it, if she wanted to do it, but not to worry about it if she didn't.)
