Beat me to it. Definitely a generational thing. A stag do was a long session in the pub, never heard of a stag weekend or an overseas trip. Although lad protocol insisted it should be the night before the wedding, no recovery time allowed.
Similar thing here, I didn't want to be hungover for the wedding so i'd arranged it for a week before and my old fella telling me that would be the sensible thing to do. So, it was just a group of around 15 of us. Off to a few of the locals, then a late night curry and a few more beers.
The night before the wedding, the old fella says me, the best man and myself should go up the pub for 'just a few'. Ended up back at my parents house around one in the morning, drinking single malt whiskey after 6 or 7 pints in the local.
It was a good job I was getting married at three in the afternoon, and a good job my mom never caught my dad after chasing him around the garden shouting "I can't believe you got him drunk!".
Memories eh?
