Wedding Reception Etiquette
You don't charge them when they visit your house - same thing. Similarly. Cash Bars have no place at a wedding reception, they are just nasty and cheap.
If you really want to cut reception costs cut down your guest list or find a venue that permits you to bring your own alcohol. The savings will be considerable and no one will be offended. What you don't use you keep.
You may choose to have a receiving line at your reception, if not, you can simply mingle with your guests. The bridal table is always served first, so there is usually plenty of time to circulate while your guests are eating to say hello and thank them for coming.
However if you do want a receiving line, here's an example of a line-up:
Matron of Honour
Seating At Reception
It's stating the obvious, but don't sit people near each other if you know they detest each other. Families should be grouped together, friends etc. Singles are usually placed together. Who knows?
Before sending out your wedding invitations, with regards to wedding etiquette, be absolutely specific in the invitations. Find out the names of partners and spouses of people you wish to invite and get them right. This means a phone call. This is also the ideal time to inform your guests of your policy towards inviting children, dates for unwed guests and even gifts registries or cash gifts.
