I know that because my dad used booking.com last year, but when he presented the booking.com printout at the front desk - 'Sorry sir, we can't recognize that.' He wasn't late or anything. Pretty sure he prepaid too. Total nightmare - you had one job, booking.com, GTFO.
Personally given the blatant deception, plus the way they took UK/Netherlands pandemic money and laid workers off anyway [1][2] I don't think I'll ever use it. Also, Barry Diller thinks working from home is a crock [3]. I'll take my business elsewhere, GL with that Barry.
