I found 13 Hilton hotels in China for 5000 points per night:
DoubleTree by Hilton Hotel Ningbo - Chunxiao (has lounge)
DoubleTree by Hilton Ningbo Beilun (has lounge)
DoubleTree by Hilton Hotel Anhui - Suzhou (has lounge)
DoubleTree by Hilton Hotel Wuxi (has lounge)
Hilton Garden Inn Chengdu Huayang
Hilton Garden Inn Dandong
Hilton Garden Inn Foshan
Hilton Garden Inn Fuzhou Cangshan
Hilton Garden Inn Guiyang Yunyan
Hilton Garden Inn Ningbo
Hilton Garden Inn Shenzhen Bao'an
Hilton Garden Inn Xi'an High-Tech Zone
Hilton Garden Inn Zhongshan Guzhen
Would you recommend any of these for a tourist for 5 nights (I'm going status match to Diamond so will get 5th night free and lounge access)?
Most of these seem to be in industrial towns and ports out of the city center, but maybe I missed a gem or two!
