Finally got a backcountry permit for the Grand Canyon! (Escalante Route)

Here is my itinerary: Day 1 to Tanner, use area BB9 Day 2 to Cardenas, use area BC9 Day 3 to Hance Creek, BE9

Has anyone done this route? This will be my first time (and the rest of my party of 4) in the Grand Canyon; I've read that isn't generally a hike recommended for first-timers, but I'm going with 3 other in shape individuals and I feel like as long as I thoroughly prepare it should be doable. I've tried 3 years to get a backcountry permit, so I'm sure as hell not passing this up now that I'm finally approved.
