The Grand Canyon is awesome, in the very literal meaning of the word. Vegas can be fun, but since you're underage, notsomuch. The Hoover Dam was mixed. On the engineering side of my brain, it was amazing. On the eco-conscious side of my brain, I thought, "This is terrible." I never made it up to Yosemite. I saw Alcatraz from the shore, but never was bothered to actually go tour it. On the whole, I liked SanFran better than LA. Anyway, enjoy your trip.
