I am trying to pack - we are leaving on the 1-3-04 Western. My question is this - do we need beach shoes? I know that we can't wear them for the stingrays. What about at Chanakaab? I believe that you have to go down a rocky stairway to snorkle there. Do you wear beach shoes down then switch to flippers - or do you walk down barefoot? If you wear beach shoes where do you then leave them while you snorkle - where do you leave all of your stuff for that matter? Thanks!
