The 2 day tour was fabulous and I recommend it. The sight of Mont St Michel as it came into view from the bus was awesome. We had lunch first before going to the Mont and that was good but took about an hour. There were only two toilets in the restaurant so a queue quickly formed - there is a lack of public toilets in France, my only complaint. You can take a free bus to and from the Mont but could walk if you want. The actual village of Mont St Michel was fascinating but a fairly steep climb up many steps. You need a reasonable level of mobility to reach the top parts. Many, many tourists unfortunately. Beautiful views around the surrounding countryside from the top parts. The overnight accommodation at the Mecure Hotel and the meals provided were all good. On the next day was the return trip to Paris via the chateaux. I saw the chateaux of Langeais, Chenonceau and Chambord and all were different from each other but were worth seeing. The grounds of the chateaux were lovely to walk around. The guides were all English speaking. The trip was well organized and an enjoyable time was had. Highly recommended.
