Help or tips from other solo travellers would be useful, and note of any particular problems that I might have on my own. Is English widely spoken? Would I have difficulty getting around? My interest is in culture, scenery, food and cooking. I would like to get to Hanoi, Hcmc, Halong Bay, Sa pa, Hoi Ann and anywhere else that I really shouldn't miss. I plan to visit for about 3 weeks. When is best? Any useful web-sites would also be appreciated. Thanks in advance.
