I've just made a booking through the accorhotels.com site for dates in January 2013 at the Sofitel Budapest Chain Bridge. They have quite an attractive "Pay for 2, get 3" nights promo running.

When booking a prepaid rate, I normally use one of my Amex cards. However, tonight, I was only given the option of using MasterCard or Visa... (No Amex or Diners). I also note that Accor have implemented the hated (well, by me anyway) Verified by Visa / MasterCard SecureCode systems.

I wonder whether this is a permanent change? I would much prefer to use Amex when booking prepaid rates.
