It keeps happening to me that I book a room at some rate via Marriott.com. Then I have to keep checking back to see whether the rate drops--because it keeps dropping, meaning i no longer have the best rate. I then update and get the lowest rate. Is there a way that I can just have it automatically update to the lower rate? It seems silly that I have to constantly check all of my reservations every couple days to see whether the prices are now lower for the same room I had already booked.
