No Alcohol?

[lilspiker]

We just found out from our reception site that there is no alcohol permitted in the church or on the properties. Many of our friends have indicated (jokingly) that they are only coming if there is an open bar. They are joking, of course, but they do intend to drink. All of them have said that they'll bring their own alcohol if we don't provide.

How do we inform guests that alcohol is not permitted on the premises?
