We are planning a trip to Vietnam. How much time would you allocate to Hue. We are interested in traditional architecture, local culture, crafts. In interesting places we like to just sit and also to have time to walk around and absorb the local 'vibe'. Our schedule is open-ended. We are considering a 7-8 days tour with Indochina Pioneer that gives us a few days in the hill areas (Lao Cai, Sapa) and on Ha Long Bay. Are there any other areas of Vietnam you would recommend. We are both experienced and flexible travelers and prefer places off the beaten track. I am an anthropologist; we both do photography. Thanks for any suggestions.
