Staying at Art's was truly an experience! The exterior truly looks like something from a movie - beautiful creek with monkeys swinging off vines into the river, cute little cabins, and exotic plants. Totally a fun place to stay for an authentic rain forest experience. It was a nice home base for Khao Sok Park, and it was a 10-15 minute easy walk into the town of Khao Sok (with the restaurants and stuff). The hotel offered a free breakfast buffet, which was very nice.
We attended the lake tour from the hotel, which was very fun and easy to arrange at check in.
The main downside was the lack of some creature comforts - no AC made for warm days/nights, lots of bugs and lizards inside and outside (bug net provided, but it had some smallish holes), etc. If I were visiting Khao Sok again, I would probably spend a bit more and get a place with AC and sealed windows (to avoid the need for the bug net), but it was still a fun time.
