Wife and I go once a year and sometimes twice if we are lucky and I love it. Its on of the few places I can go to actually relax. Theres some stuff to do there but not a lot so its an easy place to just take it easy. A lot of businesses are closed in the summer months as the heat keeps most shoppers away but food/booze is super cheap (get a Ralphs card) and once you get the hang of the main roads, commuting is quite easy. As others have said, if you want stuff to do, you can drive to LA, Riverside, Disneyland etc.
I just pick up cheap beer and loiter by the pool. If Oasis jumps in on this thread, he knows that place inside and out and can provide answers to any questions you have.
