I've just spent two nights in the Hilton Cologne which was OK but pretty high room rates (300+ Euros for a Deluxe Room - Didn't get any upgrade either despite being a Diamond Member) I had a customer with me for whom I booked a second room but still on my bill and all seemed fine until breakfast this morning. They insisted that I had to pay for my customer's breakfast stating "Hilton tell us we HAVE to charge for anyone who's not actually a diamond member themselves". So even though a Diamond member was paying the bill AND I was paying a room rate over 300Euros I have to fork out extra for a simple buffet breakfast. Went and spoke to the Duty Manager and they were still insistent. I phoned HHonors to question this and they were pretty understanding and said techically they're right but they can't believe that the hotel didn't apply some simple discretion and waive the charge bearing in mind the room rate and the fact I'm a Diamond HH holder. The overall attitude of the staff there was very poor I have to say - looks like it's a different hotel for me when I'm back in Cologne in two weeks.
