I'm planning to do the West to East route but I'm wondering why I haven't seen an option to start at Refugio Grey via ferry. It seems most logical to take the ferry from the Hotel Lago Grey to Refugio Grey and start the W there, rather than start at Grande Paine making a full-day round trip hike. Has anyone done this or does anyone know why this is not feasible? There is a Lago Grey ferry but does it only do scenic tours and won't drop off hikers? I'm wondering if it's much more expensive than the Pehoe ferry too.
If it is actually possible, then I am wondering about logistics of having a car parked at Hotel Lago Grey. Is there a shuttle we could take from Las Torres 4 days later to retrieve our car? Or vice versa, leave the car at las Torres and take a shuttle to the Lago Grey Ferry on day 1?
