Excellent Trip Planning by Alisa Liu at Asia Highlights
Alisa did a wonderful job! She was very detail oriented, extremely responsive and answered my questions very promptly. She incorporated all of the places we wanted to visit and was able to book hotels, airline tickets and special event tickets (to the Chiang Mai CAD Khomloy Sky Lantern Festival which was sold out when I tried booking on my own.) Alisa was great to work with and I recommend that others use her for their trip planning. More

Excellent experience in Bangkok
Ying was our guide in Bangkok. She was very knowledgeable and extremely helpful. She knew exactly how to move us through crowds quickly so that we could see all we wanted to say and made good recommendations for other things we were interested in. I would not hesitate to recommend Ying or anyone that helped us at Asia highlights More
