On Sunday you have other options: a few Hotels are open only on Saturday and Sunday (eg. Hotel Lauzun on the Ile. St. Louis), between April and October (2007) the Fountains at Versailles will be playing for VERY limited times (look it up), there is the bird market on the Ile de la Cite (see Tip), and there are flea markets. Some say the less popular museums are not crowded.
I include my third eye (a videocamera) as part of flanerie since my aged mind is weak and I may never get here again. These, as almost all of my pictures, are lifted from there.
