If you travel to Phuket, you can sign up for a boat tour around the Phi Phi Islands. There are a few stops along the way, though all the boats converge on one island for lunch. Boats line up along the shore, and crowds of hungry, wet people temporarily get to stand on solid ground.
By the way, this was taken about an hour before our boat ran into a monsoon and I nearly drowned. Ah, the memories!
