5. The Inn at Rancho Santa Fe, a Tribute Portfolio Resort & Spa — San Diego
The architect Lilian J. Rice drew on Spanish, Cuban, and Mexican adobe inspirations while designing the original 1923 guesthouse in the hills outside San Diego in the intervening 90-plus years, the property has expands to a 21-acre country retreat with new cottages, a spa, “coastal ranch” cuisine, and a whiskey bar. Guests can hit the tennis courts, join a yoga class, book a spa treatment, or play a round of Rancho Santa Fe Golf Club, which opened in 1929 and is set to complete extensive renovations this November.
