I've never personally understood the open resentment of W hotels. If you don't like the concept, you have so many other brands to choose from.
I've stayed in many W's over the years and found them to be great for the most part.
W Verbier might be my favorite Marriott hotel out there.
Other notable stays include W Doha, DC, and Bali, all of which are outstanding and luxurious properties.
Like all hotels, it basically boils down to the individual property.
