This was the grand hotel of choice for the Duchess of Sussex the night before her nuptials. The five-star mansion has often been a royal haunt. It dates back to the 17th century and was the home of the Astor family. Regal rooms are furnished with antiques and plush textiles, some with their own hot tubs and separate living areas. The Astor Grill and Cliveden Dining Room are refined grand affairs and afternoon tea is a speciality. Guests can also enjoy some pamper time in a spa located behind its walled garden.
