We are a family of 5 staying in an apartment near the Louvre. We are 2 adults and three teens.We will have 4.5 days in Paris and we are arriving at noon on Sunday and plan to see the Eiffel Tower,and Champs Elysees& Arc de Tripomphe. We were wondering if would be best to do the l'open bus tour on day 1 -( Monday) or go directly to the Louvre in the morning after getting a musuem pass, and then see Notre Dame & Latin Quarter. Then day 2 - the Musee d'Orsey on Tuesday a.m. and Rodin in the afternoon, and spend day 3 -seeing Chateau Versailles and day 4 - Shopping on Thursday. Any suggestions for our itinerary would be helpful.
