Headed to SE Asia via Europe in late October/early November. Trying to take advantage of a LH J fare to make my UA status again for 2025. US passport and use the TWOV program. Intent would be to arrive, spend 1-2 days in the city, and then depart (I do have a time constraint, otherwise it would be a multiday trip). The fare is about the same to PEK and PVG. And never been to China.

Any assistance, please? (And I know that everyone varies a bit - so seeing the skyline, eating a good meal or two, I'm a walker, maybe a key sight or two, would be enough for me.)

-General question - which city is better for a quick visit?
-Thinking I'd stay at an airport hotel, so ease of transportation into the city?
-Any particular airport hotels? Marriott LTP and Hilton Diamond here. So, more than a 3* hotel. OTOH, the Marriott status isn't going away and I'll lose my Hilton status this year, so I don't need the nights; other suggestions welcome.
-Reading through the TWOV thread, it all seems very straight forward from that aspect. Am I missing anything?

TIA!
