I will refrain from offering advice about your meeting tomorrow or how to use points - there's a lot of that posted already. Allow me to make a few suggestions as to how you might enjoy your time in Newport Beach, one of my favorite places to book a property.
First, right down the hill from the resort in the same small complex as Trader Joe's is Javier's Restaurant (Mexican). Absolutely fabulous place to eat, always crowded and noisy, the food outrageously good and the service excellent. Second, Gelson's Market in Newport Beach - a supermarket bordering on fine dining takeout. Nothing like it, a real shopping experience for groceries, baked good and prepared foods. At lunch they'll carve lean roast beef and make a sandwhich for you that you'll not believe. Third, Saturday morning there is a huge farmer's market at a church complex a few miles up the hill. I think there's a least a hundred stands there covering everything grown in CA as well as a wide variety of esoteric goods. Finally, drive down Rt 1 into town and look for Rose's Bakery (actually a very good bakery, good coffee and lunch fare), make a left towards the ocean and park. Then walk down towards the ocean until you can't go any further and you're on Ocean Blvd. Multi-million dollar home overlooking the ocean and a perfect walk from one end to the other for views you can only get in a handful of spots in the world.
Oh, and if doing all this encourages you to buy enough points to come back to Newport Beach over and over again, I wouldn't blame you.
