Old thread but will update the fall 2025 trip here.
My Chinese GF used the FPig ap to get the new Marriott resort in Beidaihe next weekend at about 70% rate, of course its fall there after the Golden week holiday. (Beidaihe is 3 hours east of BJ on the beach)

Other 25 travel notes; The UA 771 flight from LAX to PEK was full on Oct 7th, waited 90 minutes for our bags at 4am arrival time. On this flight, no line at passport control, and no need for fingerprints as they are on file from previous 2024 visits. IMO, the digital entry software has improved at PEK for foreigners. Previous UA SFO flights had a 75-minute wait for luggage bags at PEK.

Also, the FPig app was used for Halloween dates in Sanya at the Taikang Sanya resort in Haitang Bay. But the app did not have better rates at the JW Marriott in Sanya city, probably cause its more of a Marriott business hotel & not a Marriott resort. Still, it's our favorite cause of the EL hospitality. Only there for a couple weeks in November.
