I think that it depends on what kind of Disney you are looking for. I too get very excited about the resorts and like to watch Disney movies to get me in that mood. When I booked the Beach Club I watched Mary Poppins, but soon realized that she would best fit in the Grand Floridian! So in that order these are the movies I would watch to get me excited about a Disney themed hotel!
All Star Movies- Toy Story or 101 Dalmations
All Star Music- Fantasia
All Star Sports- Bad News Bears?? Is that even a disney movie LOL
Port Orleans - Song of the South (if you can find it)
Wilderness Lodge- Brother Bear
Polynesian- Lilo and Stitch
Grand FLoridian - Mary Poppins, Polyana
Contemporary- Old clips of Walt Disney talking about his idea of the future!
Coronado - The Three Cabelleros
AKL - The Lion King
The other resorts not so sure about? Suggestions anyone??
I do agree with the OP, the Disneyland Hotel wins hands down when it comes to overall best DISNEY theme. I have not stayed there but visited and it definatly feels like classic Disney
