Are your dates already set?
You might consider taking one or two days off Nice and/or Venice, and either adding them to Toulouse, or just spreading them down into the south/southwest area of France. Albi, Carcassonne, Arles, Cassis, Collioure are all nice spots.
Nice is nice, but Antibes, Vence and Villefranche-sur-Mer are other places to consider staying (Antibes and Villefranche are easy to get to by train and maybe bus.)
