Never give up the opportunity for a extra day in Paris.
My work/play tour schedule ended on a Saturday afternoon, with no need to be in Frankfurt, Germany, before Monday. So, I grabbed an October Sunday in Paris for myself. No plans, no schedule.
Rain would mean museums. Sun would dictate a long walk.
On the Internet, I found a single room at Hotel Cujas, on the Left Bank near the Sorbonne and close to a metro stop for the RER train to Charles de Gaulle Airport. Reviews from other travelers suggested the hotel was just ok – it was – and I wasn’t paying for charm, so I booked at 78 Euros a night ($215 for two nights) on booking.com.
I made the correct decision not to buy breakfast for an extra 7 Euros, as the breakfast room at Hotel Cujas was too warm, too crowded, and windowless; plenty of breakfast possibilities were nearby on St. Michel, even a Starbucks and a McDonald's, had I been so inclined.
On a sunny Sunday morning, fully croissanted and coffeed, I set out in my walking shoes with a grand plan to make a big circle tour of a city I last visited about 10 years ago. I ran out of day before I ran out of city.
