While Prince William managed to keep his stag party civilised and discreet, some Britons go on the rampage abroad, waking up upside down and naked in rubbish bins, the Foreign Office said Sunday.
One stag do reveller ended up being hurled into an Amsterdam canal while others have found themselves chained to police cars or falling off hotel balconies, the ministry said.
The Foreign Office said that around one million Britons were planning to travel abroad for pre-wedding parties in 2011 but that nearly a fifth of them would not have insurance.
"Stag and hen dos are all about having a great time but the celebrations can come to an abrupt end if things go wrong," a Foreign Office spokesman said.
"Cultural differences mean some people will take offence to risque fancy dress costumes and rowdy behaviour.
"To avoid a hostile reception from the locals or even spending the weekend in jail, make sure you research your destination and know your limits."
William managed to dodge the press by holding his stag do in private. The event was only announced weeks after it had taken place.
