With Emperor Palpatine, King Joffrey and Daryl Dixon, Tampa Bay Comic Con will be a magnet for local geeks, gamers and cosplayers with their wallets out at the Tampa Bay Convention Center this weekend. The three-day celebration of all things nerdy is back again, with another lineup of artists from comic books, cartoons, science fiction, fantasy and other fandoms. The "con," as people in the know call it, is as much an excuse to dress up like your favorite characters and go people-watching as it is to meet celebrities, watch panel discussions and buy hard-to-find fan gear from vendors.But this year's fest will also be for lovers with not one but two weddings planned for Saturday. And several sessions of Nerdy Speed Dating will be set up for geeks to find their matches. Last year, the convention drew an estimated 50,000 people. This year may match that with fan favorites like Sean Astin of Lord of the Rings, Ian McDiarmid of Star Wars, Jack Gleeson of Game of Thrones and Norman Reedus of The Walking Dead.Here are some tips for making the most of Comic Con.
