After re-reading some of your posts, I would like to respectfully suggest that you try something other than the Hance Trail. You and your party do not seem, to me at any rate, experienced enough to do the Hance Trail. My suggestion is that you contact the backcountry office at GCNP and see if you can get a permit for the Hermit Trail with camps at Hermit Creek and at Hermit Rapids. I have done both the Hance Trail and the Hermit Trail. The Hermit Trail is a gem, the Hance Trail is an ordeal, to say the least, and is dangerous in spots. Please re-think your plans.
