Going outside of the Americas, HR Cape Town is pretty good. Cat 1 a total steal. I just spent 3 weeks there. They are decent with globalist upgrades, filling breakfast, location is walkable to several decent restaurants and cheap Ubers to other parts of town and hiking. Gorgeous weather. Not a lot of Hyatts elsewhere in the country, but worth exploring nonetheless if you’re there anyway.
Also PH Mendoza. Cat 4. Generous with upgrades and lots of amazing food and wine in the city. I am considering a week or so there again.
