We were on the AMA Vietnam/Cambodia tour early April 2014. We started in Hanoi and ended in Ho Chi Minh City. First of all we concur with a prior review which stated that the breath of touring from this trip could not be done on your own. Our group was in the 50-80 age range with many in their 60s and 70s, retirees, Americans, Canadians, Europeans, Australians overwhelmingly white crowd, a number of Jews and I would guess more Democrats than Republicans. There was one former US army officer who had served in Vietnam who found this to be an emotional experience, all in all an intelligent concerned group That said - this was not a vacation experience but rather a working cultural exchange.
Pre-trip suggestions:
Get the Cambodia E Visa - it is about $24 on line and will save you time in line in Siam Reap and you do not have to send in your passport. Otherwise get the Vietnam multiple entry visa, easy to obtain about $250 from any Vietnam embassy or consulate.
Well appointed room with king bed, small balcony that we never used as we sat in the common areas for viewing sights. Television is mostly ornamental. No wireless in cabins. Good air conditioning. 220 outlets. Bath/shower/toilet are fine.
