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.
