Best* Hotel to Stay @ in Las Vegas?

Hello all,

I'm going in a few weeks with a group of friends to Las Vegas. Sarging will be on the agenda. Can anyone recommend an inexpensive hotel in a convenient location that is not filled with old people and families?

I've been told conflicting opinions regarding staying on or off strip. Two places that I've found online that are young/single people oriented are the Hard Rock Hotel and the Palms. Has anyone been?
