Grand entrance to dinner transition

Most weddings I've been to the bridal party sits in their seats after they are introduced and then everyone stands at their seats when the couple is introduced. Then your DJ will most likely be communicating with your caterer or coordinator who will let everyone know when it's time for dinner and if it's buffet will call each table up. If you're doing any sort of blessing that would happen before everyone is called up.

We are doing the wedding party grand entrance, they will go to the front to stand & cheer each other on etc. because we have a sweetheart table & some of the wedding party are sitting at different tables. Then once we come out, the wedding party will disperse to their seats & we will go straight into our first dance. After the first dance we will go into our blessing then dinner. We are getting both courses at once while everyone else will be served the first course so we can eat & get up to visit tables. We will have servers to bring the food out.

Talk to your DJ, they may have a plan for transitioning! Ours had some great ideas for not only transitioning to dinner but to get people on the dance floor right away.
