So let's pretend that someone booked a trip under Free Dining. No that promotion has to be booked by December. What if, in say March, you find out that you need to push your trip back on day. Now, that day will still be part of the original Free Dining dates by the "book by" date has already passed..would you be able to push it back & still get Free Dining? Or would they cancel & re-book your trip without the Free Dining?
