SOME selected shots of that hotel in the movie are from Mt. Hood Lodge in Oregon. But it’s only certain shots, while the very next shot may be from a completely different place. You gotta know Mt Hood Lodge to recognize those particular shots.
Movies do that, mix shots from different places and make it look like the same place in the movie. I’ve seen that being done in other movies.
They also take shots from the same place and try to make it look like different places, with varying degrees of success. The funniest example was Silver Streak with Gene Wilder and Richard Pryor. Early in the film the train leaves LA which looks a lot like Toronto, then at the end it arrives in Chicago, which also looks a lot like Toronto.
