Rehearsal dinner if treating bridal party night of our brunch wedding?

I agree with PPs that if you are having the rehearsal the morning of the wedding you don't need a rehearsal meal (if it's the day before, definitely need to feed people), but that will make for a *very* long day. Also, I wouldn't underestimate how tired you're going to be after your wedding. You are unlikely to sleep very well the night before, it's a very emotional day, and by the end of the wedding you're going to be tired - as is your bridal party (especially if you rehearse that morning). You may not want to go out that night, some of your bridal party may not want to go out that night, so treating everyone to dinner the night of the wedding may not be an effective gift.

I would maybe think about a simple and easy brunch or lunch after your rehearsal. Even if its just subs and chips or maybe a waffle or pancake bar, it doesnt have to be anything super fancy, but the more you can provide for your wedding party during the wedding weekend the better. I dont remember having to pay for or find my own food for any of my meals for any of the weddings ive been in.
