What are your plans? South to North, or North to South? You planning on taking a shuttle back to the car on the other side, or are you interested in possibly doing a rim to rim to rim so you can end up where you started?
I am potentially interested - I want to do a rim to rim as my next grand canyon adventure. Last year my brother and I went from the south rim to the bottom, then back up. We took the South Kaibab trail down, spent 1 night at Bright Angel Campground then took the Bright Angel Trail up and spent a night on the way up at Indian Gardens. It was a great trip!
