We have a substantial number of guests coming to my daughter's wedding who do not drink alcohol, and are not necessarily comfortable being around others who are drinking. There will be a "cocktail hour" with an open bar and snacks for an hour before the dinner reception. Are there any other possible names for "cocktail hour" that might be more appealing to non-drinking guests, and would let them know that this hour is for them, too? And how will they know that they can also get non-alcoholic drinks from the bartender?
