It appears that there is not much interest in doing trip reports on Radisson Hotels due to lackluster interest in the program and some of the hotels.
As you probably are aware the Radisson SAS brand does a great job over in Europe and I am told some of the other Int Radisson Hotels as well.
The last report if you do a search appears to be last year.
