St Sur Syr Mur
Marsailles
both in France .. I would spend the entire time there.
or perhaps jump a train the last 2 weeks to look around. Play it by ear, and sleep on the train.
(or) if you want to get your feet wet.. Palma De Mallorca, an island off the southern coast of France that is part of Spain. It's a very popular " Holiday " spot. I spent 2 months there once. Even in wintertime it was great. Got to ride Trumps huge cruiseship wantabee too.
as far as Paris... I've been to France like 14 times and never even wanted to go to Paris...... so don't assume that Paris is everything.
good luck and have fun... wish it was me
