Five of us (2 adults in mid 30’s, 1 adult in 60’s, 2 kids of 6 years) are flying into Phoenix airport in the morning of 8/11 and flying out of Phoenix at 3 PM of 8/18. Besides the air tickets and car rental, we do not have anything else reserved. We have no intention of seeing Phoenix. One of three adults wants to stay at Las Vegas for at least a night. We want to see much as we can (Grand/Glen/Bryce Canyon, Sedona, Flagstaff etc or we are flexible to change everything up based on suggestions) but we do not want to rush and can't do too much walking with two six years old. If you were in my shoes, how would you plan the trip?
