After a $450 million, three-year, lobby to roof renovation and restoration, the Plaza Hotel is welcoming back Eloise, a longtime favorite guest.

Indeed, today, the Eloise shop will open on the Concourse Level of The Shops at The Plaza. As irresistibly engaging as the fictional six-year-old heroine herself, who "moved into" The Plaza in 1955 with pet pug Weenie, turtle Skipperdee and her "mostly companion," Nanny, the 2,100 square feet Eloise shop is designed to delight both young and old.

Playfully decorated to be faithful to Eloise's indomitable spirit and distinctive color palette of "Eloise pink" and black, the 2,100-square-foot Eloise shop resembles a 'playhouse,' an homage to one of the most lovably precocious fictional characters ever. Eloise fans may re-enact their favorite vignettes from the "Eloise" books and movies. Guests can relax in the stylish living room, and plan their (mis)adventures with the concierge, just like the fictional character did in her namesake books.

In the Fashion Room guests can dress up in costumes and transform into mini-Eloises while modeling their favorite looks from a podium. In the Library Room, guests may enjoy "park views" and watch their favorite Eloise movie clips, play on the computer stations or enjoy story time with their mostly companion. And of course, fans can't leave without a visit to the Tea Room where family and friends can come together for tea and birthday parties and other celebrations. A visit to the Beauty Salon rounds out a day of living like Eloise. In Spring 2010, tea and birthday parties, beauty salon service and etiquette classes will be available too.

For shoppers, the store offers a wide variety of Madame Alexander dolls, Eloise books, Eloise-inspired bathrobes and bath towels, and exclusive product lines including the Eloise in Paris doll. The holiday debut will provide shoppers with an assortment of special holiday gift items including an exclusive Eloise ornament, Eloise at Christmas book and holiday-themed dolls.

In Spring, 2010, the Plaza's website will launch an Eloise fan club with highlights such as a section that shares Eloise's favorite things to do and see in New York. Also available are two Eloise overnight hotel offers: the 'Live Like Eloise' and 'Live Like Eloise Slumber Party' packages (for booking information visit theplaza.com). And since everyone "absolutely looooves" Eloise, The Plaza will introduce an Eloise themed suite designed by Betsey Johnson to debut 2010.

Designated a New York City Landmark in 1969, the Plaza Hotel is also the only New York City hotel to be designated as a National Historic Landmark. There are numerous additional boutiques in the Shops at the Plaza, including Ghurka, Kenneth Jay Lane, Douglas Hannant and Anna Hu.For reservations, call (888) 240-7775 or visit www.theplaza.com.
