Will my guests enjoy themselves responsibly?

Hopefully your guests will celebrate your wedding and enjoy themselves.  If you have any concerns that some may go too far and risk ruining the reception for others, talk with your venue.  There are ways to restrict alcohol consumption by specific individuals, and to slow consumption by all guests.  The venue may revert to only providing alcohol over the bar, revert to only providing light beer, not permitting shots of spirits, making all spirits unavailable, supplying people with a glass of water with every alcoholic drink, etc.  Such actions are not intended to limit peoples’ enjoyment, but to help ensure they enjoy themselves responsibly.  Plenty of water should be available, particularly since this is now a legal requirement of any venue that serves alcohol.  If you have any concerns at all, you should discuss them with your venue.
