I’m so glad we booked with Asia Tour Advisor.We paid a small deposit through One Pay and balance as services were paid when we start the tour. Since I had been to Bangkok before, we opted for 6 days for visiting Chiang Mai and Chiang Rai. It was so much fun and an efficient use of time. That was a good way to see a different part of Bangkok and keep cool in a hot city. An experience I will never forget and definitely worth the money and time.
