I believe that it was said earlier that the player can get to the orange islands by boat, plane, or surfing. This stirred a thought in my head. Will the boat and plane have a real time clock and you have to wait for several days in the real world for the boat or plane to land in the orange islands? And if you choose to surf, will there be small islands that you could stop at with pokecenters on them? If it is just one really long stretch, it would be almost impossible due to the amount of wild pokemon out in the open sea.
Highly doubtful.
I'm sure you would just sail right away.
Who would want to stay on a boat for 7 days?
