Marina del Rey

Establishment neighborhood
Ritz-Carlton, Marina del Rey
4375 Admiralty Way, Marina del Rey
Granted, the location isn't the most convenient to the center of the city, but this five-star Ritz has its appeals: For one, it's on the Marina, which is a nice backdrop for sunset drinks; for two, it's close to Venice, and the only nice hotel option south of Santa Monica; and for three, you can generally get really great deals on rooms, despite all the luxe amenities (pool, gym, spa, et al). It's a great option for visiting grandparents, as there's plenty there and in the surrounding area to keep little ones busy.
Kreation Juicery Venice
4716 Admiralty Way, Marina del Rey
The people behind Kreation Café, a certified green eatery specializing in dishes made from local farmers market produce, have applied the same philosophy to their juice bar. Juices are made with 100% organic fruits and veggies purchased within the same zip code. The result is deliciously fresh juice for whatever you're craving or need (detox, energy, etc.). They also have "juicemobiles" for those who can't make it to one of their brick and mortar locations (Venice, Brentwood, North Beverly Hills, Beverly Hills, and the Valley), and cold-pressed juices and cleanses you can order online.
