On the other hand, if your letter includes, "I would LOVE to see such things as CoH-themed rides at Disneyland," as an expression of why the idea of CoH becoming part of the Disney family excites you, I doubt it would offend them. It's not trying to tell them how to use it, at that point, but showing starry-eyed hope and excitement over the wonderful things you think Disney might do (and that would excite you, as a paying customer, to see).
