(FORTUNE Magazine) – ) ''For me it was a great experience to put on a ringmaster's outfit.'' This from Jonathan Tisch, 33, the president of Loews Hotels. Along with FAO Schwarz President Peter Harris, 43, he hosted a kids' power breakfast and circus at the Loews Regency hotel in Manhattan, home of the adults' power breakfast. Proceeds went to benefit the Big Apple Circus, a popular charity. Among the 300 kids and adults who gathered on a Saturday morning in October to munch minicroissants and shake hands with Danger Mouse, from TV's Nickelodeon, were Jonathan's father, Postmaster General Preston Robert Tisch; advertising honcho Jerry Della Femina; and politically ambitious real estate mogul Donald Trump, with his first lady, Ivana. Trump got a chance to work on his handshake. Problem is, Donald, Danger Mouse can't vote.
