Lan was an excellent guide. We requested an airconditioned mini van as we were a group of 4. He was knowledgeable, polite, gentle and had excellent English. he told us his families story about the regime. We visited the Killing Fields and S21 prison,(extremely sad) Royal Palace and Markets and had a lunch at a good restaurant recommended by Lan. This tour makes you appreciate the people of Cambodia and their struggle. Would recommend Lan!!
