Sardinia or Corsica for a 4-5 day break in February?

What do mumsnetters think? Anyone been? What's the weather like? Will it be warm enough to wander around? We like sightseeing and eating.

I would go to Sardiniaas it is carnival. Always wanted to see the sartiglia in Oristano.
Been to both, but not in winter.
Both are lovely, Sardinia has ancient sites and Roman remains and is very interesting.
