We would like to spend at least 3 nights of that time on Ko Yao Noi, for peace and relaxation. Would it be better to stay the full 6 nights on Ko Yao Noi, and do day trips to the places named above, or would we be better trying to stay a few nights at Railay / Phi Phi to get a feel for those areas?
Would we miss out on anything - e.g. atmosphere, sunrises, sunsets etc if we didn't stay on Railay / Phi Phi and only visit them for daytrips?
What would you recommend?
