Houston Chronicle (Internet / Print) 02/20/06 http://www.chron.com/disp/story.mpl/life/society/3671123.html Perhaps it's the "Secrets of Venice" theme or the masked ball aspect, but the annual San Luis Salute, Paige and Tilman Fertitta's nod to Galveston Mardi Gras, sold out weeks before invitations were mailed. To accommodate those on the waiting list, the blowout gala is being moved to the more expansive San Luis Convention Center next door. More guests mean more money for the party's beneficiary — the University of Texas Medical Branch at Galveston. Happy news to honorary chairs Dr. J. Marc Shabot and Dr. G.S. Raju of the medical center. And now there's room to spare at the evening that will feature a seated dinner, the La Festa del Luna Orchestra, the always-festive opening salvo by the Philadelphia Mummers and the unmasking of ball guests.
