One would love but:
Inquired about a points upgrade to suite for 1 night at Cologne today and the German reservations agent (dialed the 01805 number) started of with telling me that there would be a minimum stay requirement of 4 nights to do so.
I just laughed at her and told her that I never had to do that and that using the 6000 points to do so would be sufficient to do that for 3 nights.
She then confirmed that she was able to reserve a room that doesn`t require her own made rules. HaHa, sure you can just do never admitt you were wrong.

My be they start to invent new "enhanced" rules.
