Morning After Brunch

We are having a morning after brunch at the hotel where we blocked rooms ---- my question is that FH family is all from Boston - aunts , uncles, cousins, etc - he has a huuuge family and we were gonna do the brunch by invite only, like for our immediate families, bridal party and then family members from OOT that we are really close with; so everyone that is staying at the hotel would not be invited to teh breakfast. Is that rude?? We just feel like we have to draw the line somewhere. What do you guys think??? Honest opinions please

Honestly... I've been to a couple of weddings where they have brunch and I'm usually too hung over to get up for it. I don't think anyone is going to be offended! People wont want to get up and make themselves presentable.

I'm having a brunch that starts at 10AM and I'm starting to think that I don't even want to go to it. Irish receptions go till 4:30 in the morning... But I can't drag everyone to Ireland and not have one!
