How to deal with disorganized Maid of Honor? Should I leave the wedding party?

There's nothing wrong with telling the MOH you didn't have enough notice - it was really dumb on her part to plan it for this weekend. But I don't get why you'd decide to drop out of the wedding party. One has nothing to do with the other. I do think you should try to make the bachelorette party, but there's no reason you can't tell the MOH your budget limit.
