I’ve stayed at both and like both. But very different hotels. Palacio is smaller and more boutiqueish. The Westin is bigger and more grand. Both had good breakfast. I didn’t get much of an upgrade at the Palacio. Room was fine though but definitely no suite either time I stayed. The room was ok size, though we did have three folks so that may have been a consideration and maybe we did get upgraded to bigger room cause of my status. Only stayed at Westin once and got a wonderful upgrade to a huge suite. Staff at both were great but I would say Westin maybe just a bit better.
