You do not need any season tickets for the buses on the Cote d'Azur. They are already absurdly cheap to us folk living in rip-off Britain. It costs just 1 euro 30 cents to take the 2 hour bus journey from Nice to Cannes, with lots of wonderful stops en route (including Graham Greene's Antibes). For 90 pence you cannot go much further than 5 stops in Britain, but for the same 90 pence you can go from Nice all the way through Monte Carlo (the bus stops just yards from the harbour with all the millionaires' yachts) and on to Menton just a mile short of the Italian border.
