Siem Reap, Cambodia
I had my own car/driver and tour guide for one. The guide spoke excellent English and was very detailed in her description of where we visited. Although dearer than some local available tours I still think it was worth the extra for a more personal tour. A must to visit.
It was a great day out taking approx 12 hours. The boat ride in Halong Bay was perfect and a seafood meal was supplied. There were only 5 of us on the day trip and we had a boat to ourselves. I would highly recommend this tour for anyone who doesn't really want to spend 2 or 3 days on a boat looking at the Bay, which I felt we saw most of what needed to be seen in 1 day.
Seeing the Terracotta Warriors is a must see in your life. The day trip was well organised and the guide spoke very good English. Well worth the money.
I rang the free number, as pre advised, and waited where told. Wait was minimal, but as the van was full I got a bonus free tour of Paris dropping off other people.
