If they like a drink (or several) and a party, indeed it's a good place to go.

I've been to Shetland 7-8 times for holidays, lovely place, but not really in the winter. Apart from anything else the crossings can be really rough, or cancelled altogether if the weather is bad.

I only did the ferry from Aberdeen once in really bad weather, they handed out leaflets to everyone getting on saying it was "at the passengers own risk"!

Lets just say, even several of the crew were seasick on that voyage...
