you can proabably get st regis at $170.
thought great wall could be 100$ or less.

so st regis is realtively pricy, but not too expensive in real term (compared to 300-400$ in other locations)

also, st regis location is not bad, on par with great wall
(great wall is 5-10 min closed to teh airport, and st regis on the 2nd ring-road and 5 min from the 3rd-ring road / "highway", whiel great wall is ON the 3rd-ring road. but st regis closer to the tiananmen)

both great wall and hilton and pretty old and in the same cluster (location). they are about the same quality. i tend to think hilton quality is a bit lower though, but they are close enough to compare.
