On stag dos

I’m not sure if I understand the idea of stag/hen weekends away. I mean, in some cases it is obvious – go away where no one knows you in order to get laid one more time with a total stranger before you make your vow of fidelity and, at least in theory, have to give up that kind of behaviours forever (but then why take your friends with you – after all one of them could say something to someone on another drunken night and your other half could still find out).
Anyway, that reason being out of the question, what’s the point?
Paul’s just been on one in Munich and what they did was: drink beer, go go-carting, play football in the park, drink some more beer. All of which they could have done over here without paying an arm and a leg for flights and hotels. I would have understood if they had done one thing that was actually about Munich – but they didn’t! Unless you count drinking beer, that is...
Two years ago another friend of his was getting married and they went to Amsterdam, which made sense as the point was for the said friend to get stoned braindead as he loves to get stoned so Amsterdam was the place to go and he couldn’t have done that over here. But this one?
Don’t get me wrong – when/if it comes to my hen do, I would love to go away somewhere with my friends. But I would see something of the place on top of merry making...
