AHHHHH!!! incredible. we have just returned from koh tao to bangkok, 1am on the 17th. i think i really dislike the looong bus trips and since flying seems to be even cheaper, chang mai will be by flight.
Diving was great and we have a video of our first time ;) sharks, stingrays, barracudas, turtles, many schools of fish!!! couldn't ask for more. we met a great group of people who went through most of the instruction and diving with us! can't wait for more! heading up north for some cooler weather and then on to laos and cambodia!
