Yikes, Monaco is expensive to stay in, but nearby France, so best bet is to do a day trip there, or just stop while passing through. There is a MacDonalds in Monaco with its famous cheap food,lol or you could buy makings for a sandwich and some fresh fruit in one of the supermarkets. But France itself CAN be done on a budget. The Tourism folks there regulate campgrounds, for example, and give out stars like they do for hotels. You can stay on farms, in apartments, right on the grounds of a winery off-season, etc., for pretty reasonable cost. Traveling France this way is always a way to really get to know the country and the people and the famous FRENCH CUISINE! Steer away from Paris and the other tourist hot spots and do your research on the Internet (go on some forums and make some friends there who have been, or who live in, France). Google "cheap stays in France". All the best!
