The hubby and I are going to old school road trip it without any accommodations booked, which makes me a bit nervous - find a hotel or use the tent. Possible spots we may see/drive through - Sedona, Horseshoe bend, Antelope Canyon, North Rim of Grand Canyon, Zion, SLC, Grand Teton, Yellowstone. We'll play it day by day and see what we want. I know several of those things require reservations though and will be pretty packed when we are planning on going.
