dubs? I don't know about dubs, but there are othere attractions in Vegas besides gambling. It really depends on what you are looking for. There are plenty of shows to see ~Cirque shows such as the Beatles Love... comedy, a few 'old vegas' theme shows and plenty of others ..adult and otherwise. Concerts galore. Plenty of clubs (if you are into that sort of thing). A few museums~wax museum, Titanic, Bodies exhibit(not as sexy as it sounds.. its about the human body and how amazing the anatomy is), some art, a shark exhibit..
There is an arts district that is very much alive on every First Friday with lots of freestyle artists~paintings, dance, drum circles...it's where freaks like myself like to go..
Ballet, indoor/out-door plays and concerts
There are spas to luxuriate, endless dining options, golf, shopping, Grand Canyon tours..
There are a few more quiet, not vegasy place to relax
One of my favorites is Red Rock Canyon for hiking, nature walks (not so much in the summer heat, though)~ some people bicycle, mountain climb. Desert beauty. I've seen some little funny go-cart looking things going by in groups (looks like rentals). Also Mount Charleston has plenty of hiking (great in summer). If you get the ski fever really bad, there is a resort Lee Canyon..right up with Mt Charleston.. in a pinch..
