I've dropped in for drinks and a bite to eat over the years at the Hyatt.
I would not really call it a "resort", of the Hawaii or Mexico variety, but a more of a business like hotel that happens to be beach adjacent, and I suppose a good base if you plan on being doing other things around SoCal, especially Northern OC, or Long Beach areas.
If you want a more secluded getaway with the wife, I'd recommend the new Terrana Resort in Palos Verdes next to the Trump National Golf Course. Since this gorgeous location is on a cliff, its does not have much of a beach however, but is a good place to bum out for a few days at the pools. (you can always drive about 15mins to a good beach nearby)
If you want a SoCal beach experience, then I'd recommend the all suite Beach House in Hermosa Beach the home of beach volley ball and modern surfing. You're on the beach, with plenty of activities such as restaurants, and pretty easy access to greater LA
What are you looking for? I probably have some other ideas based on what you want.
