Hi! I'm a MOB and my daughter's friends are planning a cookout and then a 'party bus' type evening for her bachelorette party. Is it normal for all the girls in attendance to chip in to pay for the bus or how is that handled? It seems really weird to me to invite people and then expect them to pay to participate. Honestly though, I've only been to a couple of BPs in my life so really don't have a clue.
