My husband and I are planning a 9 night (10-day) tour of the National Parks in Utah. We are flying into and out of Vegas (it was much cheaper than SLC. So far we are planning on staying the first night in Vegas and then heading to Zion NP. We are spending two nights in Zion and then plan to spend several nights in Moab to see Canyonlands and Arches. My question is, it seems there is a lot to see between Zion and Moab. Is it worth it to stop and spend the night in between these two destinations? Or is it enough to make a stop on the way from Zion to Moab. I don't want to eat up too much time from enjoying Zion, and the parks near Moab, but I also don't want to drive right by something that's worth stopping and spending some time at. I should also mention we are active people and would like to enjoy some of the many activities these parks have to offer (hiking, canyoneering, white water rafting, jeep/mountain bike tours, etc.) so that's why we would like to spend a couple of days (2 or 3) in the Moab area. Any tips would be greatly appreciated!
