Hi-Family of 3 is traveling to Phoenix June 25th for a week. We've planned a trip to grand canyon and now looking for something different and think my 17 year old would enjoy a 1/2 day desert jeep tour. can someone suggest a good tour and company? any advice on whether better to take the 8am or the 2pm tour- seems like most offer one or the other times. some are more western theme- confusing what might be the best. any advice greatly appreciated.
