Mr. Selfish and I had a week allocated for the western part of Thailand. We landed in Phuket but knew that we had to get out of there as soon as possible. We stopped in Khao Lak for a couple of days in order to scuba dive at Richelieu Rock and then we headed to Khao Sok to spend a couple of nights in a tree house and one night in a raft house. Khao Sok is a national park encompassing 738.74 square kilometers. It is pretty rustic and not yet overrun with tourists, which means that there are no chain hotels in Khao Sok.
Mr. Selfish has been expertly collecting airline and hotel miles and points since September 2011, which has enabled us to stay at some really nice hotels during our selfish year. Because we could not use any points for Khao Sok, I was left in charge of planning the accommodations.
For our tree house, I booked the Bamboo Orchid Tree House at Khao Sok Tree House. It had air conditioning and an outdoor rustic bathroom, and cost 4,000 baht ($136 USD) per night.
