The wife and I had never been to the Grand Canyon and on a whim we decided to cross that off our bucket list before we left Vegas. Yelp helped us find Sundance and we were happy to find that we could get a reservation on less than 24 hours notice. This was a very amazing vantage point to see the Canyon, Hoover Damn and Lake Mead.
The operation is professional and you can tell that they take safety very seriously. My wife started feeling motion sickness during the flight (pretty common they say), but our pilot did a great job of giving her tips about how to combat it and a Sprite during our lunch break in the Canyon. Those two things helped her keep it all down and make the trip memorable for the right reasons.
