La Thuile or Cervinia?

Hi,

We've enjoyed Cervinia in the past, but are struggling to find a
self-catering apartment for our vegan daughter and partner in the first week
of March. We've been offered one in La Thuile (Monte Bianco appts), but
we've never been there - could someone kindly compare and contrast these
resorts? I've read the two resort guides on the Ski Club of GB website,
obviously ;-)

Thanks,

Steve P
