The point of hotel chains, and chains in general, is the consistency of the mass-produced experience. I can walk into a DoubleTree hotel anywhere in the world and get the same welcome cookie. It's a positive, not a negative; people often enjoy knowing what they're going to get. If you prefer a more unique experience, which is perfectly understandable, then simply avoid chains perhaps?
That's my point, but extended: I feel like walking into any hotel chain (including different product tiers and luxury brands) gives effectively the same experience.
Don't get me wrong, there's a benefit to consistency of product (especially when you travel Su-F for consulting).
But that benefit, parent company consolidation, and economies of scale drive a net result of overwhelming homogeneity.
