What if you could instantly arrange nonstop interviewing in whatever field you wanted while on a fully paid vacation at a world-class resort? Would life be a box of chocolates? The two-pound box? With many almond clusters?

Then google something like las vegas convention visitors bureau. (You can't make a mistake, since any variation of this will get you the list of hits.)
There's always a listing of the carnivals comin' to town. Sometimes you click a link, sometimes you write down the name of the group, sometimes you call the phone number given. Always look for dates, host hotels, and contacts.
