Some couples love the thought of a double wedding ceremony. If your best friend or your sister or brother are getting married at the same time of you and your fiance you might consider doing a double wedding. The benefits are that you can celebrate together and that if you are shy, you can deflect the attention a bit more.
You can choose to do your own separate wedding vows or you can incorporate your wedding vows and recite them together.
