Thanks for the advice, xyzzy, and the warning, KMiami.
I may have to try the old fashion method of contacting the hotel with my questions.
KMiami, we will be in the UK for 14 days and the price of hotels - not to mention everything else! - is enough to make me take any free nights wherever I can. I will, however, watch for good deals as our trip dates get closer.
