I have been using, LJ biz ,for almost 8 years and 10 trips and have always enjoyed excellent service. They have organized trips for me to PP and Angkor Wat in Cambodia ,,one that I highly recommend ,,and also Veiteine Laos and all over Thailand from Chaing Mai to Phuket . They have always had everything arranged perfectly ,and there was never a problem with the arrangement as hotels were what they were said to be and guides were always spot on and helpful.
I also rely on their knowledge of Thailand and all the sites and places the recommend , They got me to such diverse sites as the market that a train ran thru to the Elephant Festival in Surin . So if you would like to see some very special sites in Thailand , just ask them they are always happy to make a tour ,custom fit to your needs.
