to see a group of drunken revellers seeing how many people could swing on the tail boom
Well, small boys have small helos, big kids have 'big' helos.
Unfortunately, 'human condition' is such. Especially drink-related alteration to somehow decent behaviour gets bit too obvious on British Isles. English, Scottish, Irish, pretty much the same certain kind when drinking.
upmarket hotel? Well, money can buy cars, clothes, expensive stays, but it doesn't buy manners.
No easy way around this. One idea though.
The ones of you flying as a leisure activity, bring along male au-pair, nephew, neighbour's son to mind the helo while 'on business'. If they're young enough not to mind few hours alone or old enough to pretend they're the owner-pilot to passing-by girls, even better.
