I'm sure you've heard of the classic stag destinations and activities but if you want something a little different how about trying one of these:

Fly like a bird!

Go skydiving without using a plane by hovering like a Malteaser above a huge fan...safe(ish) and a great laugh.
> See facility operators in the stag do directory.

Oktoberfest

Fancy being surrounded by loads of blokes getting hammered with girls in lacey bodices serving you fresh 'steins' of ale? You do well why not viisit this German instiution.

Dubai rugby 7's

A couple of days in quaffing a few 'cold ones' in guaranteed sunshine watching world class sport. There are also more night clubs and bars in Dubai that you might think!

Piss up in a brewery

Believe it or not, there are several breweries in the UK that actively encourage you to get lashed on the premises...don't be accused of not being able to organise one again.
