If you already have a Rewards Card (not the Credit Card), you can transfer earned reward bucks to the card either on-line or by phone. Either way, the transfer is nearly instantaneous. If you need to order another card, I'd be sure to have at least 2 weeks for it to be mailed to you (some arrive faster, some even slower). Better yet, if you need a new card, visit one of the Disney Rewards service desks at WDW with your VISA and a photo ID and they will give a "fresh" card, then call Chase toll-free and transfer your rewards to your card--it's easy!
Chase's website has a link to the Disney Rewards information that gives step-by-step instructions, too.
We're earning points left and right this time of year with Christmas purchases...working toward using these rewards for some "Extra Magic" when we travel to WDW late this summer.
Enjoy your trip and your rewards!
