I am very happy to complete this trip with Ren. It is a perfect and unforgettable experience. Ren is a great guide, professional and very attentive. He patiently helped us discover various creatures and explained them carefully. We were very lucky to see orangutans and hornbills. Great job by the special chef, lunch and dinner were great! Finally must mention Mrs. Ren, she is a very good cook, unforgettable taste. Joe
