Hi all...Planning a trip to Arizona to visit family and friends. Created the schedule below.

I would appreciate any ideas on what not to miss (sites, lodging, dining, parks, etc)
and if you think the driving, etc is unrealistic.

All help is much appreciated. Thanks!

Day 1 Phoenix to Yuma;
Days 1-3 Yuma (Mexico, Sand Dunes, Prison, etc);
Day 3 - Yuma to Scotsdale;
Day 4 - Scotsdale to Sedona;
Day 5 - Sedona then Flagstaff;
Day 6 - Flagstaff to Grand Canyon;
Day 7 - Grand Canyon;
Days 8-9 Down to Tombstone / Tuscon (Via Coronado Trail?);
Day 10 - Tuscon to Phoenix
