I have 7 days booked on Koh Tao with my girlfriend in April. Our initial thinking was we would move to another part of the island for 6 days before getting the night train back to Bangkok. I am now considering trying to hire a car in Chumphon and exploring the area around there for 6 days . Just wandering if we might find some less touristy beaches and things to do. Does anyone have any advice or knowledge on whether this would be worth be trying? or maybe it's better to just chill for the whole two weeks on the island?
