So I have been doing some reading up on Ko Samui and for the most part it seems pretty safe. Dont trust people, stay out of the jungle, watch out for jet skis, and don't get stung by a jelly fish and die. Seems pretty reasonable... oh and wear bug spray because the mosquitos will eat you alive and give you crazy disease that induce vomiting, headaches and fever. And thats all if I survive the civil unrest in Hong Kong.
