So how would you suggest they do a “boutique hotel” that is “highly themed” (your words, not mine) for Epcot? Genuinely curious, not trying to hammer you. I just don’t see what they could do at this point to make it “special”. They’ve abandoned the original “futuristic” theme for Future World and replaced it with Bob’s Movie IP Inclusion theme. Could they try to go the nostalgia route? Yes, but it would make them look kind of silly in the process.
I can't speak for that poster, but my idea would be to add a real hotel wing to the existing [fake] Hotel du Canada. You would enter the façade in the park for check-in (in the former gift shop space), have a tea room on the 2nd floor and then a hallway leading behind the pavilion to the actual rooms. All keeping the 1880-1920 Railroad Hotel aesthetic.
