"Again" since there have been a few threads recently and again for me, return trip. My dates are flexible, starting around mid-January or later, ending no later than mid-March. Probably 4-5 weeks total.
Shanghai or not? This will almost certainly be my last trip to the area. I know there's a lot of 19th-20th c. Jewish history, but I don't know much more. This would be my last stop - hoping to avoid winter weather. Is there enough to warrant a 4-6 day stay?
Vietnam I visited briefly on a cruise. 1 day tour from Danang (My Son temples, Hoi An village, etc.) and 1 day in Saigon (museums, Chinese market) and a 1 day Mekong Delta (mostly boat) tour. I would like to see more of Saigon and the rest of the country, probably with a small group tour, geared to older, less adventurous travelers. After my short time there, I'm not sure I'd be comfortable on my own for very long, even in the major cities.
Thailand I would like to go back to Chiang Mai and Bangkok. Suggestions for one other area that is easily accessible for 3-5 days (been to Chiang Rai, not interested in beach time)? I'm quite comfortable on my own in Thailand.
Hong Kong/Macau Return visit to see more. Is it worth the hassle and expense for a Chinese visa to visit Guangzhou? I just checked the Chinese Embassy website ($25 on an Israeli passport, $140 on a US passport - wow). Even a 2-entry visa is $40 vs. $140. - so now my question is simply is it a worthy destination if I'm already in HK?
