Put in a deposit for the current sailing and check once in awhile to see if it goes down. Just be aware of the cancel date so you can back out if you decide the rate isn't good enough. Most travel agents will do this for you but I would ask just to make sure as they prefer to upgrade you and keep the price otherwise they make less commission on the cheaper price.
