When Del Mar Racetrack’s horse racing season begins, so does the stampede for rooms at L’Auberge Del Mar, a posh nook in Del Mar. Winter is ideal for appreciating the hotel’s trifecta of outstanding dining, recently refreshed lodging and relaxing spa. Setting: Nearly hidden below busy Camino Del Mar’s cafes and boutiques and above 15th Street Beach, home to a pocket park and surf break.
