The wedding officiant will give the bride and groom, wedding attendants, their parents and any readers the cues that they will need. The attendants will be shown what order they will be walking in and who they will be partnered with (if any) as they walk down the aisle. It's a great time to go over any last minute details such as what time and where everyone should be on the wedding day.
After the rehearsal, everyone gathers together to toast the bride and groom. The rehearsal dinner can be as casual as you like or as elegant as you like. It can be held at someone's house, restaurant, banquet facility, etc. The choice is up to the host/hostess. It can be as casual as a backyard barbecue or as elegant as having it at a beautiful banquet facility. No matter where the host decides to have it, it will be sure to be a fun time for all!
The immediate family, wedding party attendants and their spouses and significant others, the parents of the child attendants, and the officiant and his/her spouse are invited to the rehearsal dinner. It's a good time for the two families and your friends to get to know each other a little better. It's also a great time for the bride and groom to express their gratitude to their parents and wedding attendants.
You may choose to give thank-you gifts to your attendants and your parents at this time. Most importantly, it's a time to let them know how much it means to you for them to be part of your big day.
