We're going to Paris with my mother next week for 8 nights. We've been before and did the most touristy things (Louvre, Eiffel Tower, Versailles), so looking for other ideas. She cannot do beach (for health reasons she can't be w/o shade for long) and doesn't want to do chateaus again (which eliminates most side idea trips I've seen when researching). We're staying close to Gare du Nord for part of the trip. She speaks intermediate French.
The problem is she gets tired easily, so she needs to rest often. I'm looking for things to do in Paris and within 2.5 hrs train ride (train and long cafe visits count as resting) that are a little off the most traveled path. Giverny is on the list.
Thanks in advance and sorry for the last minute request :).
