I booked this tour through my travel agent Tour East, they did not disappoint. I wanted to make sure that I was on a boat that did not squeeze you in like sardines. (I have had such an experience before to Phi Phi and found it most unpleasant.) However this tour there were a maximum of 23 people on the boat, plant of room, english speaking guide, lovely morning tea, and lunch provided, with plenty of bottled water on hand. THe island is beautiful and only 20 mins from Krabi.
