The son of very very dear friends of ours is getting married. A few people have said no and we know they (our friends, not really their son) would be really disappointed if we don't go.
But:
4 hour drive away
Wedding is at 1pm which is smack bang on both our kids nap time (they are 2.75 and 9 months)
We will have to leave at around 6.30 to get the kids back and in bed in our hotel room. Neither are going to fall asleep at a wedding reception, no chance.
It's just such a pain and for anyone else we would say no.
