I'm confused. Many hotels in Rome charge a lower rate if you pay in advance with a non-refundable stipulation. One particular hotel that I'm zeroing in on lists such a reduced rate on their web page but when I attempt to take advantage of the lower rate, I'm told the rate is not available. I guess they may make the reduced rate available at some future time. My concern is that if I book at the higher rate now (I want to make sure I have a room), will I be able to take advantage of the lower rate if it becomes available at a later date? Any ideas/advice?
