My wife & I will be renting a car to explore Normandy and Brittany in mid-September. A possible midpoint between the two appears to be Mont St Michel. Rick Steves' France 2017 seems to suggest that a good way of seeing the island is to arrive late, stay overnight, and leave the next morning, to avoid the crowds. My questions are as follows:
1) Does an overnight stay allow enough time to enjoy & appreciate the island, including its famous tides?
2) Is there enough to see on the island if we stayed on it for two nights?
3) Whether we stay for one or two nights, are there secure parking facilities on the mainland for our rental car? (Rick of course recommends that no valuables be left in it). If we stay on Mont St Michele for two nights, will leaving the car on the mainland be a problem?
Thanks for any help here...
