I have an ambitious thought to hit as many of the French Riviera towns as we can into one day. We are on a cruise that docks in Cannes for 10 hours. I plan to use trains to get around. My thought is to go straight to Monaco, then to Nice, Antibes and Cannes. I know I will only have 1-2 hours per town and just want to walk around and see the highlights. We would not be planning to see any museums. I can always slow down and skip the last few towns if it looks like I won't get them all in and just take the train back to Cannes to get back on the cruise ship. Do you think it is possible? Am I setting myself up for failure?
