Many of those people didn’t like it that much until the visited and changed their mind once they did.
The resort really looks and feels very different when you're there close up, as opposed to seeing it from afar or pictures. It's much prettier in person.
For those that lament the "grey" of it.... Catching the sunlight up close, it never even looks gray to me.

It’s a popular resort with both owners and non owners which is why 7 month bookings go fast.
I certainly get not everyone likes it but as already mentioned, not everyone wants or needs the big Disney theme that some other places have.
