Thanks to ALL of you fro the great Detective work!!
Reposting Slowhatch;s excellent link here:
La Digue maps: traditional map here and interactive map with panos (called "rotographs" ) here (be sure to turn off the music first).
These 360 pano's include the ferry, the jetty, the tortoises, the ox-carts, the helicopter pad, and some other places we might see as well. Great pics...it was a little slow to load for me but worth the wait!!
Also spec that we MIGHT see teams use the inter-island ferry as well as the helicopter as we know crew used boats between the islands for sure.
