What would be a decent time to budget for the following, considering I am on a three-day trip to Paris?
1. Hôtel des Invalides/Napoleon's Tomb
2. Musee Rodin
3. Musée d'Orsay
5. Centre Pompidou
6. Musee Picasso
7. Basilique du Sacré-Coeur
8. Cimetière du Père-Lachaise
Which of these are must to do, and which of these can I skip in case of time crunch?
