As a solo traveller, I booked the 4d/3n tour with Travbond. From the booking phase 'til the day I left, they were amazing. My guide John, young English speaking guy, was fantastic: as I told him I was interested in a photographic tour, he tried to find each time the best place at the right time (early morning, late afternoon) for taking pictures. The accommodation at the Kool Hotel was perfect too. Temples around Siem Reap were amazing, Tonle Sap Excursion just average.
