I love to read TripAdvisor reviews and in two of them, I read about a phenomenon that surprised me very much. Upon check-in, a HHonors member overheard the receptionist offering walk-in guests of the Hilton Arc de Triomphe a walk-in rate of 110 Euros, a rate you will never find on the Hilton web page for that property. With the Hilton Charles de Gaulle Airport, a guest writes that his walk-in rate was 56 % of the cheapest rate offered on the Hilton web page.

Is that a specifically French phenomenon or does anyone else have experiences with extremely cheap walk-in rates like these?
