I have an idea. This is what I did when deciding that I do want to rent a cart. I went to google earth. I zoomed in on the campground and looked at the cabin areas and where the Meadows Recreation area and the Settlement Recreation area, as well as other areas are. Then I put googleman down and selected a place and selected "walk" and it told me how long it would take the walk from various areas. I decided that it would be worth it for us because especially at night, or if I'm rushed for any reason, its nice to not have to walk.
Also, the day after Christmas we ate at Trails End for dinner, which we loved by the way, and then decided to walk around the nearest campsite loops to look at all the fabulous holiday decorations that the campers had put up... oh wow..we only were able to get through the 2 loops closest to the Settlement Depot. It took longer to walk through than I thought, and then we were in the way physically as we walked in the road, because there was golf cart traffic constantly coming through. I really at that point, wanted a cart, but then I didn't really want to go to the Outpost to rent one. (my friend who works there was going to be with us with his cart but he ended up with the flu). I decided I'm just going to consider that part of my cost for my Thanksgiving vacation. I want to go through all the loops to see the decorations.
Oh, and don't skip watching the fireworks from the beach. There are patio tables and chairs along the beach/dock area to sit at. They pipe in the music and it is really very lovely. We did that after dinner and it surely sold me on staying here instead of borrowing forward my next years DVC points for our Thanksgiving stay.
