We booked Happy Angkor Tour based on Trip Advisor and couldn't have been happier. Sok Chea was our guide. He is knowledgeable, personable and took some great (trick) photos. We started our one-day tour with sunrise at Angkor Wat. Sok helped us avoid the crowds which is no easy feat! We then saw Ta Promh (as featured in the movie "Tomb Raider"). After a delicious lunch at a restaurant Sok chose, we went to off-the-beaten path Ta Nei. So cool!! We ended the day at Angkor Tom. The Bayon temple was the highlight. Our driver Sal made it easy to see a lot in one day. If you're fortunate enough to be going to Siem Reap, I recommend hiring a Happy Angkor Tour guide.
