Please, please, pleeeeeease can we have more Harry Potter guests! Maybe the Phelps twins, Evanna Lynch, Warwick Davis, or Matthew Lewis! Also, it would be fantastic to see more Doctors, like Sylvester McCoy, Peter Davison, Colin Baker (again, as I couldn't afford his autograph at the first one :'(), or if we're lucky, Tom Baker . The more Doctor Who guests the better, it would be fantastic to see more of the new DW stars too, as it is filmed in Cardiff after all!
