Vientiane to Siem Reap Destination Reviews

I'm sorry to say but the travel experience was shambles. I chose an option of travel only by one bus to save moving from vehicle to vehicle, but ended up having to change multiple times: sleeper bus, van, another van, third van, another bus. We had to walk between the borders ourselves - in the heat and with all luggage, and after Cambodian border we had to wait for two hours to be picked up being told they don't know how long it's gonna be - maybe 30 minutes, maybe another 30. That was when contacting the agency as there was no one to advise on the other side besides a gent at the only local place there saying that the operators would come at some point. The arrival was to be 17:45 (though someone else bought the trip as 17:00 arrival, another 18:30) but ended up being after 21:00. The gent from the agency and Cambodia drivers were nice, but the staff on the sleeper bus in Laos rude.

For the price wise, the trip were acceptable because we arrived our destination without any accident. But there was too much vehicle changes ,which we needed to carry around our luggage and there was only one break time for lunch. I mean there was no time for toilet and few minutes break to stop by local shop on our way. I respect their hard work of the driver and passengers ,our patient.

They booked me 2 seats on sleeper bus so no-one was next to me and water was given. We left on time. Free tuk tuk from the bus stop in Siem reap to our hostel. The only thing I can criticise is the 2hr 30 wait at a car park in Pakse. Thankfully other girls were on this bus because I would have not wanted to wait here alone at 5am.

The sleeper bus was VIP and great and the lady at the terminal was extremely friendly, assisting us to get our tickets and take us to the correct bus. Once you cross the border you are told to wait at a coffee shop, however it’s non functional and we waited best part of an hour here. You are then put in a minivan which takes you to a restaurant. We had to wait here for two hours, and was told we’d be on the first bus to Siem reap. Of course, more and more people turned up and we saw people getting on buses to Siem reap before us despite our group being left at the restaurant over an hour longer than those. Once we arrived in Siem reap we were told we would get a free Tuktuk to our hotel but BEWARE as the guy who got us in his tuktuk(once we had loaded all our bags and were sat waiting to go) wouldn’t stop trying to sell us his other tours and then said we needed to cover 3 USD for his gasoline for the ten minute journey. After a 24 hour travelling day this is NOT what we needed.
