Yes, Guest Relations at any Theme Park or at DD can help. We purchased it this week at Epcot. Cost is $60 ($25 more if you want a 2nd card). This week, DDE changes and wil be called Tables in Wonderland, but is otherwise the same program. As always, the card will not expire for 13 months and the current list of participating restaurants is very similar to past participants.
We've used the card three times and have already recouped most of the cost. You'll need your AP (or proof of FL residency) and a photo ID.
