In particular I’ve had great luck with Marriotts it’s Shanghai and Shenzhen. I was surprised since Marriotts are nothing special in the US.
A friend’s Marriott room in Hong on the harbor was also great, but I didn’t stay there.
The great thing is you also benefit from permanent elite status, which makes it more affordable and the stays even better with the lounge, free food, etc.
For example, in Shenzhen (tech hub next to Hong Kong) you can get a room for well under $150/night—less than some SV rents monthly. Pay with a hotel/travel rewards card and you’ve got something good going. I’d seriously consider doing this if I didn’t have wife/kids, but pretty happy with things now.
