Hotel Bel-Air

This elite and quietly decadent Mission-style '20s hotel, a deamy getaway on 12 fairytale acres of lush landscaping, reopened in 2011 after a major two-year overhaul. The additions—which include new lofts and hillside suites, a La Prairie spa and fitness center, plus upgraded room features—are impressive, but thankfully the overall vibe hasn't changed much: Guests still enjoy spending long afternoons by the pool, meandering through the gardens or subtly trying to spot which Hollywood player is sitting at the next table in the Wolfgang Puck restaurant.
