Whatevet you pay to get to the Grand Canyon is worth it, Steph. I think it is the single most impressive thing I have ever seen and we have been to the Egyptian Pyramids, Mayan Pyramids, Niagara Falls etc. We took teenagers to Vegas with us. They wont let them stand and watch the gambling The staff come up and say "move along there" or "no loitering with minors" but we found other things to do ( and frankly anything that kept Terry away from the slots was good!). The dolphins were at the Mirage when we were there as was the show with tiger ( name escapes me for the moment). You must do one of the shows ( Vegas style!), not cheap but must do.
