Overall very good, Vietnam Cambodia 7 days tour, in Vietnam to Hanoi, Halong Bay, Ho Chi Minh City, the main attraction is Halong Bay, known as the sea Guilin; Cambodia's attractions are Siem Reap's Great Angkor, Little Angkor, and a self-funded collapse column, all three of which are stone piled buildings and carvings. If you choose a place in Vietnam, Hanoi will be fine, because it will arrange Halong Bay for one day and one night. If you have time, Ho Chi Minh City will also go, because it is just a one-day trip. Of course, there is a place in Da Nang that is said to be very good. I have not been there yet.
