Probably too late to change plans for those going to Paris this weekend but apparently lots of places will be closed on Saturday: Gilets jaunes, acte IV : Paris ville morte ce samedi - Le Parisien

For those who don't speak French: the titel is: Paris, ghost town on Saturday. Eiffel tower closed, lots of musea closed (Louvre, Musée d'Orsay, ....), shops strongly advised to close, pubs asked to keep tables and chairs inside
