Over the last couple of months I've had both my American Express and my Visa cards used by other people and had to have them replaced.
No, I didn't have them stolen and they were in my possession the whole time.
I knew that somewhere I had used them had gotten hacked.
And today I got a letter from Destination Hotels explaining that they had indeed been hacked and anyone whom had stayed at any of their properties between Jan. 1 and June 15 of this year had been compromised. And the Tempe Mission Palms is listed as one of the properties.
So that explains what happened with my cards. I suggest everybody who attended the Phoenix Forum and had a room and/or used their card on the property get themselves new cards immediately.
