I know that cash bars are frowned upon here on TK, but I feel like in our area they aren't all that uncommon, and I'm having one at my wedding. Most people attending are local, so I don't think it'll be an issue, and I've posted all the information, including that I'm having a cash bar, on my wedding website, to give people a head's up.
However, I've been attending school halfway across the country all year, and a number of my friends (about 4-5 people) are driving up for my wedding. I'm not sure what their expectations are as far as the bar goes, but I do know they plan on drinking. I gave them invitations and told them to check out the website, but I'm not sure if they actually will. I would hate for them to get to the reception and be unprepared to pay for alcohol. Is there anything else I should do as far as tactfully letting them know there's a cash bar, or have I done everything I should in letting telling them to check out the website? I just feel bad since they're driving halfway across the country for our special day and I want to make them feel welcome. I'm fairly confident that any other OOT guests will not be surprised, as they're from the area and moved out of it; these friends are from Florida.
