I believe we will go to Six Flags. No other plans yet.
I have been to Vegas with kids, not teens, but we had a lot of fun. If you rent a house with a pool that can be a nice way to get away from the hustle of the casinos. There's a canyon near by that you can hike, plus roller coasters and that one hotel with the water park. Teens might appreciate the shows and good restaurants too. I think vegas is fun for everyone.
