I know this is an old thread now but I’m obsessed with W Hotels and have been looking for a list like this. I’ll add that my hometown’s W Hotel closed in 2021. The W Washington, D.C. is now the Hotel Washington. Upsetting that the closest W to me is now the W Philadelphia.

W New York Downtown has also closed, among many others. Those are just the two Ws I’ve stayed at which have now closed.
