I'm planning a 3 night FFN stay here at the end of March - rates seem to be 640 euro/ night on the days I've checked.
I've read some contrasting points in this thread so I would appreciate some clarification. As a diamond, it's clear that breakfast is comped but internet is only comped if you get upgraded to the 6th floor (an exec room?). And what if all the exec floor is full? Did no one get upgraded to the deluxe king? Do they definitely upgrade all diamonds to exec rooms?
