We are taking a 15 day trip to all of the above locations. We are camping in all of the above locations in May, 2014 over 10 days. The rest of the time is driving time from and to Texas. We are stopping by the South Rim on our way back and doing a helicopter ride. We have camping reservations at Arches and North Rim already for a week each. We plan to give back days whenever we get the middle of our trip worked out. We start at Arches since Grand Canyon is closed at the start of our trip. We are tent camping. We have three kids- 14, 11 and 9 who are all athletes. We plan to hike as much as possible. How long should we spend at each place?
