I would love to go to the Cite-Sciences museum, and possibly watch a movie in la Geode. I am having trouble finding on the Metro (Website says Metro: Porte de la Villette). Is that actually a stop on the Batobus? M'aider! Actually, if there is a boat tour (which I haven't managed to work into the itinerary yet) that gets us up there, that might work, too, but I'm a little worried if we get off for a few hours, how will we get back?
