Jeremy,
there are so incredibly many things to see (and shoot) - I would try to spend as little time as possible in the car, and as much time as possible on the trail. When Bryce is a fixture for you anyway, why don´t you stay in the area and enjoy what´s there? It´s just a few hours drive from either LAS or SLC, and within another few hours you can reach, among others, the following:
- North Rim of Grand Canyon NP
- Zion NP
- Kodachrome SP (which, however, I don´t like that much)
- Cedar Breaks NM
- Grand Staircase/Escalante NM
- Capitol Reef NP
- Vermillion Cliffs NM
- Antelope Canyon / Waterholes Canyon
That´s enough for a month (not just for a week)...
Oh, by the way: when you are at Bryce, stop by at the Visitor Center - I have a couple of large prints there on permanent display which you might like.
Best,
Frank
