If you don't plan ahead in this way, some caterers will try to charge you extra for your band members, photographer, videographer, coordinator, etc. Just stand your ground and remind them that your wedding professionals are to be treated as guests. After all, they are creating and capturing to film the most cherished moments at your reception. We in Mixed Company have actually had brides offer to set a table for the band along with the other guests, usually near the stage area. And of course, we try to do an even better job for thoughtful brides like that.
Musicians are very emotional creatures.
That is how they create. They might even practice before they arrive. Have your caterer set a table near the performance area for wedding professionals. This includes your band, photographer, videographer, coordinator, etc. This way, if you need something or someone needs to make an announcement, you will have access to your wedding professionals to assist you with running the microphone or snapping a photo, etc.
