I'd always wanted to visit the Rodin Museum, so I headed there and arrived a bit before midday. The building that houses the museum itself, Hotel Biron, is undergoing extensive renovations and won't be open until September if this year. (Btw, hotel doesn't mean the same thing in French as in English in case you're confused. It's like a fancy residence, often associated with the aristocracy.) My ticket was just 7,50 euros, and I made good use of it by walking leisurely through the sculpture gardens and the small exposition space still open in the welcome area of the Hotel. I stopped for frequent bench breaks and pondered the beauty of the place, the parade of humanity, and how much I could possibly sweat in a single day.
I only waited in line about 5 minutes, but the line was quite long when I left about 2:00 as you can see in the first picture here.
