This swanky Parisian hotel, located on fashionable Avenue Montaigne, blends classical French style with exceptional services for kids. Children will enjoy a merry-go-round in fall, an ice-skating rink in winter, a children's menu for breakfast and child-sized bathrobes and slippers. With two months' notice and for approximately $23,000, young guests can have a scaled-down red Cabriolet inspired by BMW's 1936 model 328.
