> the quality of the room wasn’t noticeably better than other places I’ve stayed

I broadly agree with you on their hotels. But I’d note that Four Seasons doesn’t compete on room quality, but service. If you planned your stay perfectly they shouldn’t outperform. But if you forgot something, or need help with something weird, they have a habit of being halfway legendary. (Colleague left his suit at home. They had one made overnight. Concierge apparently knew a suit maker’s cell.)
