Worth joining Goldpoints? Yes.
Worth doing anything more than picking up the occasional Goldpoint when you have to? No.
US Radisson properties are nothing to get excited about, many are just plain sad.
The program is unreliable and untrustworthy.
And no great awards.
I find it useful to transfer 1000 Goldpoints into 125 Northwest miles once per year as a Fly Free Faster partner. And you can earn 2000 points/yr just by changing your email address every 90 days...
