Wow! That's an oldie but goodie! I do remember when Eastern was the official Disney airline! That's the airline we flew in 1990 for our first family WDW trip (not knowing it had just filed for bankruptcy and would close less than a year later).
We had arranged arifare, etc through Walt Disney World travel. When we arrived in orkando, there were a couple of characters there (Minnie and Chip, I think) to meet us. At that time, the airlines were serving meals and the Child Breakfast came in a bos with the castle on it, plus a couple of other small goodies.
