There will be 3 including a 15 yr. old boy. Trip time will be 16 days. And we are driving. Its meant to be an educational trip. Museums, famous homes, national parks, etc.
I will look some stuff up and reply in more detail tomorrow.
Cheers!
I really would encourage you to visit Arches NP:
http://www.nps.gov/arch/
right outside Moab. Over 2,000 natural arches in the park. Moab is on the Colorado river and has river rafting etc. Moab is also a center for mountain biking and has the Moab jeep safari where jeepers test their equipment.
On the way to Moab is Green River, UT, the site of the best watermelons in the world (IMHO). Festival every Aug.
GW mentioned the Shakespeare theater in Cedar City and that is great with performances daily. (Its not THAT out of the way-GW)
