The Eiffel Tower and the Louvre are the two most disappointing tourist destinations in the world, according to this poll.
I can see why the reportedly glacially slow process of ascending the Tower might detract from some tourists’ enjoyment, though I don’t think it would from mine (I’ve been to it but not yet up it).
But the Louvre? How could anyone possibly be disappointed by the Louvre?
My guess? These tourists march in to see the Mona Lisa, find a smaller-than-expected painting behind plexiglass and obscured by a clot of viewers, are disappointed by that, and march out without seeing much else.
