and not very accurate...
Shenzhen Crowne Plaza is in the middle of Shenzhen bay - Manila Crowne Plaza and Holiday Inn are about 500m away from their actual buildings and in Seoul, the COEX Intercontinental and Grand Inercontinental are about 500m away from the actual buildings - and they are just the IHG hotels I have checked as I have them already marked as personal placemarks. Out of a sample size of 5, that's 100% wrong and wrong enough to make it difficult to locate the real world hotels if you were using Google Earth to find your way around.
I installed the file, but I am not very impressed with the placemarks.
