This hotel provides information at the Orly airport information desk that they have rooms for day use, at 15 euro per hour. But when you go and try to book one, the guy at the desk says no day-use rooms available because they are fully booked tonight. But, if you ask if you can book a room for the night, he smiles and says “oui”! And how much is that? 151 euro. He already knows you’re leaving in a few hours, he can get it cleaned and check another guest in for the night, and charge the full rate a 2nd time for the same room/same night. Seems like a bait & switch technique.
