Hmmm, I have had the fortunate experience to go to attend a stag weekend and a hen night. (There in lies a big difference
)
The Stag's do involved a weekend of activities revolved around paintball, beer, and strippers. The Hen do was a great night out.
I like the "surprise" element of the Swedesh night out, but its the same all round (in my limited experience). Mainly it depends on the best man and how good his imagination is. I have heard of instances where the stag was locked out of his hotel room naked and worse.
'The hen night was more like one of the best nights out ever, but no real "mean" stuff. Although we did all dress up like we were in Starsky and Hutch which was punishment enough...
I'm all for mixed parties, as long as everyone except the stag/hen knows whats going on
.
EDIT: Fuck I'm a lousy speller
