Minibars, room service, and spa days are nice treats for hotel guests, but how about living the life of a superstar for a day? Some upscale hotels are offering creative packages where guests can bask in the glow of the paparazzi, spend a weekend like a famed secret agent, or recreate the experience of a heroine in a romantic comedy. At Row NYC, for example, guests can pay $2,500 for a taste of the glamorous world of a celebrity.
