I called this morning and found out that they still do "Dining with an Imagineer." Its at the Brown Derby, they do both lunch and dinners ($60.99 and $99.99) in a private dining room. They usually have a few dates available each week and book 30 days out. You need to reserve with a credit card and there's a 48 hour cancellation policy.
Not for everyone, but I'm hoping to book this as a special treat for my DH's birthday in Nov.
