We're making plans for a Spring Break trip to Arizona with children ages 14, 13 & 12. My wife decided we were driving after weeks of fruitless search for an airline deal! Anyway, we've got the framework for the vacation in place and I'm asking if anybody has any suggestions for sights that are highly recommended. Here's what we currently have planned: Sat & Sun - Drive - arrive Flagstaff Sunday evening Monday - Flagstaff area - Observatory Monday Evening Tuesday - Grand Canyon - South Rim Wednesday - 12 hour tour of Grand Canyon by air, boat & jeep! Thursday - Drive to Peoria, AZ for 1:05pm Cubs ST Game Friday - Phoenix area - head back towards home in PM. In conclusion, I'm interested in anything anybody has to say regarding things to see on the drive to and from, as well as things between Phoenix & Flagstaff. Thanks in advace!
