Hilton certainly uses historic events in its hotel promos, e.g. the Chicago Hilton for its association with the 1968 uprising.
As far as the earlier comments about deceptive price quotes, I had a pretty outrageous experience with Minsk Avis/Budget. They did not include mandatory fees in the quote, then insisted on 2!!! forex surcharges (quote had to be in USD, then converted to EUR, then to BYN). By the 3rd contract change, I've had enough and turned it down -- politely explaining to the girl that the practive was annoying and unacceptable, even if the quote were still competitive. I rented a car the following day from SIXT. By contrast that experience was just adorable. I got practically a brand new car delivered to to the hotel, and charged exactly the quoted price at better than market conversion rates. Initially the guy even made a mistake in my favor using the EUR/BYN rate instead of USD/BYN. I had him fix it, so he would not get in trouble later.
I certainly agree that chain hotels in Belarus (both Hilton and Marriott) must be paid in points to get the best value. Those who need to pay cash would be much better off staying at local boutique hotels.
