As the nickname implies, Tinseltown does indeed sparkle--or maybe it's just the flashes from the paparazzi. Be ready for your close-up if you check into Chateau Marmont on the Sunset Strip (rooms from $335; chateaumarmont.com). Everyone who's anyone, including Charlize Theron and Scarlett Johansson, has stayed, partied, or people-watched here. To keep a lower profile, opt for the Farmer's Daughter (rooms from $159; farmersdaughterhotel.com) in West Hollywood, where gingham decor and flat-screen televisions cheekily (and chicly) co-exist.
With actresses honing their bodies for the big screen, there's no shortage of celeb sightings at local gyms, but you're in Southern California, so enjoy the outdoors! Go hiking in Runyon Canyon Park, a rugged 130-acre reserve slicing up the Hollywood Hills. For surf and sand, drive up Highway 1 to Malibu, where you can jog beaches abutting some of the priciest real estate in the country.
Finally, why not treat yourself--while saving money for a shopping splurge on Melrose Avenue--at the Rescue Hand & Foot Spa in West Hollywood, where Cynthia Nixon, Felicity Huffman, and Teri Hatcher have all had their nails buffed and painted ($60 for a manicure and pedicure; rescuespa.com).
