Viking's excursion around Paris before sailing

[likestoread]

We will be sailing on the Viking Pride--Paris to Normandy in June. I understand that there is an included excursion around Paris the morning of the day the ship sails. Can you tell me what sights are included in that tour? With the limited time we have in Paris-arriving early the day before- I'd like to plan to see sights on our own that are not covered during the Viking excursion.

 

Thanks.
