Inquiry Submission By eager_tourist97

Hello! Can you please give me suggestions on which bus lines to take for traveling from Ho Chi Minh to Siem Reap? Web links would be much appreciated. We?re 5 in our group which includes our parents who are both septuagenarians. We would like to purchase our tickets online so we wouldn?t have to worry about it once we get to Vietnam on January 8. Thank you!
