I have used Ibis Kassel for many years for one night on my way back to Denmark from South of France. This time I was extremely embarrassed that I had to have a heated argument in the reception, because I had prepaid breakfast for two persons, I could show her my receipt for the amount prepaid and she said that in a way I was right - the problem was only, that the manager at Ibis Kassel did not accept this, so even though I has paid for it, I could not get any breakfast - and if I was not satisfied, I could just complain to IBIS (booking system a gather??)!!!!! I was furious - this should NOT be my problem at all - if there is a difference in how the manager wants to have things and how the Ibis general hotel booking works, this cannot possibly be MY problem as I could show in writing that I had paid for it - it all ended up in her giving in and just giving us the breakfast - more or less, I think, to have a highly unsatisfied client away from the reception. There was an underlying tone that I should really be gratefull which I was NOT at all - in fact I consider to find another Ibis on our way back to Denmark next year. Also it was very disturbing when we had dinner, that there was a whole school class - or someting like that - checking in at the reception in the same area - with reading out names loudly - and apparently there was also some problems with their bookings!
