Have you had any experience with taking dock-side tours in any or all of the following cities from LOCALS, rather than Renaissance shore excursions? Hong Kong, Guangzhou (Canton), Da Nang, Ho Chi Minh, Bangkok, Singapore. Ren prices for shore excursions seem to range from overpriced to outrageous. In December, my wife and I will be doing the foregoing cities on the R2 and would appreciate any info on buying tours from (English-speaking!) locals at dockside. Many Thanks!
Stick with the group everywhere other than Hong Kong and Singapore. In the latter two places there is excellent public transportation-- both metro and buses. Contact the tourist offices for info on what to see. We took the bus to Haw Par Villa in Singapore. Cabs are also plentiful. In Hong Kong, ride the Star Ferry. It's right where you will be in Harbor City.
