As said elsewhere we booked this for 2021. I notice that day one schedule says the tour starts at 2:30 but only lists the typical welcome reception/dinner. Also it begins at the Waldorf Astoria Versailles yet no activities on the schedule for Versailles on this tour. I wonder if a late day or after hours tour of the chateaux is planned? We had an early start like this on our ESW which was used to visit Stirling Castle prior to the welcome dinner.
The 2020 Normandy tour was supposed to start at 3:00 but it did I have a Chateaux tour sked for the morning of day 2. I doubt any of the 2020 tours happened but wonder if any of those who were booked have any insider knowledge on this.
