It is a bilingual tour, not English tour
First of all this is a bilingual tour; 80% Mandarin and 20% English. If you are not a native Mandarin speaker, you will feel left out. They used 5 diff buses in 4 days, 1st 3 days buses very average quality. It is a tourist exchange; every day you are on a different group, guide and bus. Changeover communications were vague, not electronic, caused confusion at Las Vegas. Only one guide explained the spots visited; rest were on and off. Food stops were at too small pumps - very few options. Our experience was mixed. By and large the guides were courteous.
