This place is awesome! I've gone to a shooting range with a shotgun before, but this was my first time shooting some sport clays. I would recommend this place even for beginners. I was there on a Friday with some friends, and they have a Friday deal for a free cart rental (usually $25/hr).
The only recommendation I would make is for the pros to give a brief tutorial on how to reload ammo into the gun that's rented. I wasn't familiar with the semi-automatic they gave us, so we spent a good amount of time out on the first station trying to load in ammo.
All in all, a really fun place. It wasn't busy at all- in fact, we only saw one other group out on the entire course during the whole day. I will definitely be back during my next Vegas trip!
