Part Palladian country house hotel, part lively resort, and part luxury wellness retreat, Grantley Hall is set on 30 acres of parkland, combining grandeur with glitz. Bedrooms are large and traditionally elegant in shades of taupe and aqua, and marble bathrooms have giant showers. There are three restaurants: a fine dining room run by Michelin-starred chef Shaun Rankin that specializes in set price, locally sourced tasting menus; an all-day informal Modern British restaurant with dishes like pork belly with carrot puree and Josper Grill dishes; and a buzzy cocktail bar that serves pan-Asian food and features a live DJ. For those who want even more nightlife, there's a below-ground Art Deco-style late-night Champagne bar featuring live jazz on weekends. The huge spa has a wide range of massage and beauty treatments, a two-story gym, an ice bath, and outdoor sauna, and and indoor-to-outdoor hydrotherapy pool. But the real draw is the 60-foot marble-clad colonnaded swimming pool.
