"Are the Radisson Hotels affiliated with any program - do they give any miles anywhere?"
Oh, do we have an answer for you.
Yes, the are affiliated with a program - The Worst One. And yes, they do give you miles, but only after they give you a big headache.

Well, really Radisson hotels itself are not bad at all, and they do have a very fine chains Radisson SAS in Europe and Edwardian in Britain. The problem is - their loyalty program is a disgrace and they have shown a blatant disregard for their only hard asset - customers.

One may stay with'em, but any long term affinity is out of question.
