We are booked this fall on the Paris and HOF tour and we are all set for touring attractions not covered by RS in Paris proper (arriving a few days early, plus we have been to Paris before).
Q1: At stops after Paris, are there any must see sights that we need to pre-book tickets for our free time?
Q2: At Mont St-Michel, how difficult is it to walk to the top? I can walk miles, but my knees hate stairs/steps :-(
Thanks in advance!
