I know that Fantastic is close, as in walking distance - but they "only" do the snorkeling trip, I want, they don't seem to arrange trips to Khao Lak. We (two boys age 8 and 11, and I) would like a day trip there.
Do I have other good options for trips close to Merlin?
Also, a small practical question... I don't expect spa-like conditions ;-) But I assume there's some kind of "bathrooms" both on khao sok and snorkeling trips?
