Hello, I am planning on a trip to HCMC this end of April and would like to go to Siem Reap as well. I read about Mekong Express bus to Siem Reap on different times. However, I would like to know if this Mekong Express bus has a daily service between HCMC and Siem Reap. I read somewhere that it goes only on certain days? is this true? please shed light on this. I only have a few days in this trip so I would like to plan out everything and get to know the exact bus schedule. Thank you!
