We've done the Park n' Fly from a few airport hotels near Portland International Airport and this is by far the nicest, cleanest and most comfortable. It was quiet, well appointed and the shuttle to and from the airport was timely and the driver friendly.
The sleep number beds were very comfortable but... somehow we had 2 remotes that operated the same bed... leaving the second bed stuck in the settings it was on when we arrived. Minor problem though and the beds were still excellent.
We will definitely return to the Radisson PDX if we are in the area again.More
