Could you find out what hotel they're staying at and call and pay for a room upgrade? Maybe contact a family member and arrange a car service instead of a shuttle if that was what they were planning to take. You could get a celebration package through Disney if they're staying onsite, but those can be pricey.If they're offsite or probably even on site you could arrange a gift basket through a company like MouseShoppe that would be more customized to what they like and the situation. Also, there was a thread where someone recommend some photographers that will do vacation pictures, you could try to arrange a day with one of those so they get family pictures, or maybe a gift card for a day's photopass or speak to a family member and ask them to register all of their ride photos and you can buy one for them when they return.
