So, we booked our first trip to the world already, but they've just announced the free dining deal. We're still going to go for the deluxe dining package, but if we had waited to book until now, we'd be saving nearly $500... but how do I change it so we see the savings now? Do I have to cancel our current reservations? Or, can I get them to apply the savings to our current reservations? All help is very appreciated!
