Chris is right, I spent a lot of time in south of France and Monte Carlo is very nice and romantic expensive though.

Nice is like Brighton, without blokes in figure hugging tops.

Cannes is good, sandy beach? It's "thin jumper" weather in February too If you stay at the Hotel Majestique de Barriere you won't be dissapointed think it was in one of the bond films too. [theres a pretty smart brothel 5 minutes round the corner if your missus don;t put out ]

Barcelonas a brilliant place but theres a bit TOO much to see if you aint been before, your missus may wanna keep going out, so there may be less hotel room action

Defiintely Cannes or Monte Carlo, quiet, pretty and the French there are MUCH nicer than the parisiennes
