I'm in a Hyatt (Istanbull) right now. Not sure about free/paid masks from the counter as I brought my own and haven't asked for one, but one was in my room along with a sanitizing wipe and I would assume once i used it, it would be replaced with a new one. They are asking people to wear masks in the hotel, with signs up everywhere. Hyatt Regency LAX also had signs up and made sure to tell me to use my mask when not in my room or actively eating, but no free mask in my room (didn't ask for one). They also had no market open, but if you asked for amenities (like toothpaste, floss, soaps, etc...) staff brought them up to the room after about 10 min.
