So many companies do the same tours of Phi Phi islands and the surroundings gems at roughly the same price, but we're glad you did it. We say 'once in a lifetime' due to the amount of tourists that visit it daily, but we've had a few guests that come and visit us in Thailand, so we have been a couple of times. Still loved it as we love anywhere with sea, sun and sand. Good to see you'd enjoyed yourself! :)
