We have no option but to split one day of our trip to Paris to Versailles & Notredame/St. Chapelle.
For less queuing & better effiency, would you advise us to go:
1. Versailles at 9.00 am, Notredame & Sainte Chapelle after lunch.
2. Notredame (8am opening), Sainte Chapelle and Versailles after lunch til closing time.
We'll be going next month in June, and already purchased Versailles Palace Ticket online.
