Last night we attended at travel talk at Wide World Books on Patagonia. It was given by Wildland Adventures. They do several trips in Patagonia both Chile and Argentina and they have a hiking trip that has a very similar itinerary as our trip.
It was great to see slides of the trails we will be on. The hike along Lago Grey goes through a more lush rainforest area along the side of the lake to the Glacier. The hike up Frances Valley is more rough. And the hike to the base of Torres Del Paine looks great but the trail is not cleared and maintained. There are a lot of bolders to walk around and at the end you end up climbing up talus to get to the base. But what a view. They also had slides of the accomodations which we will be using in the Eco Lodges and the tents. Of course, the hosterias look nicer but this should be an adventure.
I also found this great photo journal of a similar trip. There are also wonderful photos of the hikes. Check out the hike up the scree on the Torres Del Paine Lookout
