Siem Reap
This place was amazing. I think it was my favorite city in SE Asia that I visited. We got a tuk tuk driver one day and let him take us anywhere he wanted, and it was one of the best days of our vacation. Ankor Wat at sunrise was something I'll remember for the rest of my life. Some of the places we went we felt like we were there too long, but I could have stayed in Siem Reap much longer.
Insider Tip:Rosy Guesthouse in Siem Reap is the best place I've ever stayed in while traveling. Also, the best meal we had was at Butterfly Garden. Make sure the souvenirs you get are made in Siem Reap, a lot of them are shipped in from Vietnam or Cambodia.
