Terrific tour guide that organized the Krabi 1-day 4 island tour! Em speaks English very well and his entire tour team was very friendly and helpful. I *Highly recommend* doing this if you're in Southern Thailand. It was about 2000 bht to travel from Phuket Town (one-way) and see all those amazing islands. Definitely a must-see ... think of it as seeing the "Hawaii of Thailand" =)
