We took our kids and they loved it. We were on a road trip to the Grand Canyon and just decided to try Vegas since we were so close. The kids had more fun there than anywhere else. Now my kids are younger so I am not sure about a 13 year old. We stayed at the Excalibur which has carnival games in the lower levels. They loved the sharks at Mandalay Bay, tigers in MGM(also Rainforest Cafe), shopping and shows in Ceasar's, all the theme park rides in Circus Circus. All the free shows at night on the strip they loved. Also the roller coaster at New York New York. The Excalibur, Luxor, And Madalay Bay are all connected so you never even have to go outside. With the New York And MGM just a short walk away we could avoid some of the trouble that happens on the strip at night and still have fun. We only walked the strip at night once and did not run into much trouble though, just a few people handing out flyers with graphic photos, my kids are young enough that we can distract their attention from looking. Don't forget all the great shops like the M&M(my kids favorite) and Coca Cola. Out of that whole 3 week trip they loved Vegas the most and keep asking when we are going back.
