We used XUAN last year and were thrilled with him! Yes, he was higher than we expected, but his service is top notch and professional. He is passionate about teaching visitors about his county, without being pushy. I booked 1 full day in HCM City and we were there with my FIL who fought in the war and has lived with PTSD. Xuan went out of his way to show us sites that were not on a "tour" and as kind and compassionate as anyone could be. He had a full lunch which was delicious. I know I could have paid less for another tour guide, but for us, he was worth it and I'd do it again.
