I do love how everyone makes out a bucks/hens night is like something from the Hangover. Most of them are just a big party to impress old, depressed married people
Personally I think the bride/groom should be able to do whatever they want. If they want to meet up, have a joint function, whatever they should. End of the day they will be spending their lives together, so you don't want to do stuff that will cause trouble.
The way some people talk this up, may as well go to a knocking shop. If you want to see a set of boobs, go to a strip club. It just seems that most guys are that whipped that the only way they can justify it is by saying it is a bucks night
