Thanks. Wife is calling their information line tomorrow.
And now for a couple of tips for the OP:
(1) Trim your toenails before you go or start the hike. If they're too long it will be painful as you start the long walk downhill.
(2) It's a dry climate, and altitude of 8,000+ ft. holds even less humidity. Take twice as much water as you think you'll need. I bring a 3L water pack (Osprey) and my wife brings a 1L bottle for these kinds of hikes. Drink often because if you dehydrate it makes it harder for your heart.
3. Bring moleskin or bandages & ointment in case you get blisters on the hike. I wear Smart Wool hiking socks--do not wear cotton socks. They cause blisters.
4. Take a lightweight poncho. Not only good for keeping off rain, but gives some windchill protection too.
