It may be late October, but temperatures are still hovering around 75 degrees in California and Nevada. Where to unpack? Thanks to hotel deals from Vacationist, try Ravella, an Italian-inspired resort just 17 miles from the Las Vegas Strip, where the outdoor activities are a welcome counterpoint to Sin City's nightlife-oriented pleasures. Meanwhile, Terranea Resort, on 102 acres just 16 miles south of LAX, has all the fixings for a warm-weather escape: Pacific views from oceanfront terraces, two Jacuzzis, a 9-hole golf course—even a 140-foot water slide. Or for something more intimate, there's the charming, 16-room Hotel Les Mars, in Sonoma, a one-block walk from downtown Healdsburg.

Ravella – up to 19% off
Lake Las Vegas, Nevada

The Venetian, on the Las Vegas Strip, isn't the only place where Italy is re-created in Nevada's Mojave Desert. Consider Ravella, a sprawling, 349-room resort on the shores of Lake Las Vegas, just 17 miles east of Sin City. Here, Tuscan-inspired architecture evokes old-world grandeur, while a white-sand beach, Jack Nicklaus-designed golf course, and dozens of hiking and jogging trails mean that travelers spend plenty of time outdoors—with frequent dips in the pool, of course. The best rooms are in the Bridge wing, designed to look like the Ponte Vecchio, while the Firenze Lounge is the spot for small plates, including sliced prosciutto and Italian olives. But unlike the Renaissance city, or even Venice's condensed version on the Strip, at Ravella, you'll end the evening casually dressed, roasting s'mores at the open-air fire pit.

Terranea Resort – up to 35% off
Rancho Palos Verdes, California

In 2009, a developer turned the former site of the Marineland theme park in Palos Verdes into a Mediterranean-style seaside resort with a 50,000-square-foot spa. Although it offers excellent children's facilities—unusual for such a sophisticated property—Terranea is all grown up, with a golf course, restaurants and lounges, and stately upholstered furniture in the 582 rooms, suites, and villas. Nearly every angle maximizes the Pacific Ocean views: you'll see the sand from the three pools, spa treatment rooms, and most balconies. (Sale ends in 2 days.)

Hotel Les Mars – up to 35% off
Healdsburg (Sonoma County), California

Hotel Les Mars, an intimate 16-room hotel, evokes a French maison, complete with hand-hewn-walnut wood in the library, as well as fireplaces, four-poster beds, and 18th-century antiques in all guest rooms. Guests receive a daily in-room French continental breakfast of fruit and fresh-baked pastries, as well as invites to daily wine-and-cheese pairings in the hotel lobby, when they can mingle with other travelers and, occasionally, local winemakers. Though serious oenophiles often head four miles west to explore Unti, Papapietro Perry, and other wineries in the Dry Creek Valley, the hotel is one block from Healdsburg's downtown plaza, where there are more than 20 tasting rooms and a host of high-end boutiques. (Sale ends in 6 days.)
