If it's just up and down to the South of France why use a jet?
I'd opt for a King Air 90 or a TBM850 if you can stomach single engine.
Both are well proven machines, perhaps a little slower but certainly a lot cheaper than a jet!
The King Air 90 GTi with a coffee maker and toilet on board, splash out on communications (iPad and wifi?) and "wow-factor" interior and you could still afford a drop dead gorgeous stewardess as an extra still for a lot less money (and more time!) than the jet option ..
(fly in the mid to high 200's region (above most weather), 1400 nautical miles range (almost 2500 kms), assume 270 TAS)
