Vegas is just Vegas, go and see and judge for yourself, you'll have a blast that's for sure
I stayed at the Excalibur and the Luxor hotel, they're worth a look, but don't lose your money by doing too much gambling, a little bit is nice to get the Vegas feeling though
If there's any possibility to go to the Grand Canyon, GO THERE!! And take a helicopter flight, it's expensive but an experience of a lifetime
