In reply to maybe_si:
We went after New Year and flew Easyjet to Catania.
Took at about 3 3/4 hours to drive from Catania to San Vito. Lots of roadworks on the motorway across the centre of the island and snow on the way back!
The Catania hire car set up at the airport is a right hotch-potch, especially on the car park return, so make sure you know where you have to take it back to.
