The Madame Tussauds website is currently offering 50% off the Merlin Annual Pass. So for £75 you get into places like Alton Towers, Thorpe Park, Legoland, London Eye, Dungeons, Sea lifes etc for a year. Considering it costs £38 to get into Alton Towers and £36 for Thorpe you've pretty made your money back by just going to those two! Its only on until 10th January 2010.
