I have studied Italian for two years now, and may be coming to Cagliari for an 'au pair' work/room and board exchange this January ('07) thru May or June ('07), and I am looking for advice on the best ways to get to Cagliari (cheapest and most economical). Is it better to fly into Cagliari? Or somewhere else in Italy and take a ferry? I'm also possibly interested in taking a class at the University while there, so if anyone is familiar with the university, I'd love advice on that too. Thanks!
