I don't think this "open letter" is gonna cut it. Hey, if you stayed in one of our hotels in this 7 month period, your information might have been disclosed to unknown persons. The number of hotels affected is limited, but we're not going to tell you which ones, or if your information was potentially leaked. Therefore, we're just going to ask all of the guests who stayed in any one of our properties worldwide to monitor their credit card statements and let us know if they notice "any suspected unauthorized card activity". And if you visit our web site, we'll tell you how to get 12 months of free monitoring of your credit reports.
What about the mandatory disclosure laws in some states? I'm quite certain that Radisson has hotels in those states and it's highly likely that some of the residents of states with mandatory disclosure laws stayed in an affected hotel during that timeframe.
Radisson, Please join the 21st century.
BTW, I'm glad that the only time I've stayed in a Radisson in the past 12 months, that the trip wasn't booked until June 2009, and it was booked through Expedia (or other travel service). Of course, Radisson did get my credit card upon check-in, but I don't remember if they swiped it or simply did a paper imprint, and it was in June, which is supposedly after the timeframe when the leakage occurred.
