Very hard and interesting question!
I would start first with location questions. What parks do you spend most of your time visiting? Do you like the idea of bus service or monorail service?
then I would probably go to amenities questions - do you prefer a resort that has sit down restaurants or food courts? (personally, we hardly ever eat at the hotel dining spots so the type of cuisine available isn't really a selling point for me.)
DO you intend to use the pool? do you require a spa? do you desire a robe to be provided? is 1 sink sufficient or do you need 2? Do you want the shower/toilet separate from a dressing area? do you want a private balcony?
I like the questions about liking the beach, eclectic, nature, tropical, or victorian - laid back or more formal -
Of course, at Disney you have to include price point questions. That determines MANy things for MANY families!
Not sure color scheme is a big deal for many - but maybe light/dark is more the question.
Should be fun to see what other questions people come up with!
I see alot of quizzes online that try to help people choose a resort by answering some basic questions like:
