Booked an upcoming AMB FWNC Fri, Sat at the IC Paris Le Grand, Fri was 50EU < Sat. A few days later I cancelled and rebooked to take advantage of a better rate and noticed before cancelling that the reservation had been changed ... the 2 nights were adjusted to be the same price ... 1/2 of the 2 night total. Obviously I'd prefer Fri to remain lower as Sat would be the night that gets zeroed out.

First time using one of these certs ... is this expected ? is this how it works ? Don't see anything in the T&C mentioning "price averaging"
