Start of the day we had no line @ Skyliner IG-DHS. Honestly didn't figure out how to get to the walking path until our check-out day. Now we do - the path goes right by the Clown Pool. then follows the water - easy.
End of the day we had no line for Skyliner, DHS-IG - easy choice with tired feet. YMMV, but you'll see it at DHS and can decide if you want to wait for the boat or want to walk if there is a line. There was a huge line @ IG to go the other way though.
