I would do at least 2 day stays, but somewhat understand your desires. I usually prefer only hotels with ELs.
-My 2023 favorite in Beijing is the Weston on 3rd ring in Chaoyang, but best BJ stay in 2023 was the Hyatt regency in Chaoyang for one night, (i needed to burn two free Hyatt nights due to expiration issues) And the grand Hyatt is dated & poor EL service.
- Sanya, see the threads, only made about 7 stays there of all the Marriott brands since 2009. many are dated now, but some new Marriott luxury brands need visits. the 2023 favorite is the JW in the city, the only Sanya Marriott resort with an EL, which has fabulous food & service.
- Best 2023 new Marriott resort hotel on the ocean is in Beidaihe, only a couple hours by train from Beijing. Hotel web site pics are true, this resort has no EL, as most Marriott resorts don't.
