Many years back, a family stayed at the Disneyland Hotel. Like most parents they had purchased their children plush toy souvenirs. The first morning, when the family set out for their adventure at Disneyland the children left their toys on the bed (most likely to catch some extra sleep).
After a long day at the park, the family returned to the room to discover the toys were not on the bed where they had been left. Frantic the children went through the room looking for their cherished toys to find them in various places throughout the room, Mickey was hanging by his hands off the shower curtain, Mini was on the floor looking up at him and Pluto was in a corner with small balls and a bone. It had seemed as if the toys decided to have some fun in the hotel while the children were away.
Some time after their vacation had ended, Walt received a letter from the Parents. They wanted to thank him and his staff for such an amazing vacation. The part that really stood out to Walt was the fact that the children were even more excited each day to get back to the room to see what they would "catch" their toys doing than the excitement for the park.
Those parents and kids were fans thanks not to the billions of dollars of rides, fantasy worlds, advertisements but thanks to the efforts of a housekeeper at the Disneyland Hotel.
