Overview of the plan

Here is the plan so far for September 2011.  I am planning that this should be a Monday through Friday but I will not know until I can get the reservations.
Day 1: Leave Phoenix and stay overnight on the North Rim.  This will either be in a hotel or camping (depending on what I talk Kent into).
Day 2: Start down the North Rim.  I plan to start as early as possible so as to enjoy the hike and get to the bottom before the sun sets.  We will then stay that night in the dorms at Phantom Ranch.  If you also plan to have dinner there then your reservation needs to include it.
Day 3: Spend the day at the bottom of the Grand Canyon and enjoying the short hikes there.  I am planning to buy breakfast, lunch and dinner there.
Day 4: Leave to hike up the South Rim.  I am planning to also buy breakfast and a sack lunch this day.
Day 5: Stay overnight on the South Rim at either a campground or hotel (again depending on what Kent wants).
I am planning that my stay at the bottom of the Grand Canyon will be about $200 (unless I decide that I need a steak dinner).  This will include 2 nights in the dorms, 2 dinners, 2 sack lunches, and 2 breakfasts.  My thought in buying the meals there is that I will not have to carry as much stuff then.  3 days of food could be heavy.  I also am planning to refill all my water at the bottom therefore I only need to carry one day of water.
Please let me know if you have any questions.
I cannot wait for this adventure.
