I was looking at my statement on line, and I noticed what seemed to be a very large charge for my last stay. When I pulled up the folio, the amount was just what I had expected. However, on the HHonors pages, recent hotel activity, it appeared that I had paid about double what I thought. Naturally, I got points for everything.
I called AMEX, and their automated system indicates that I was charged the normal rate for the room.
So, it appears that Hilton has given me double points for a double charge (I got about 6400 points for the stay from Hilton), but the actual amount I pay is just what I always do.
The net, with booking bonuses, double points, etc. comes in at about 84 points/$
Please make more mistakes like this.
