Its funny this old world isn't it. I got my first Annual Pass in 2003 which got me into Alton, Chessington, Thorpe, Madame Tussauds and Warwick Castle for £85. This got me into all the events that the parks put on and I got free parking. Wind forward twelve years, I can now get solely into Thorpe Park and free Parking and entry into the parks is a perk of the Premium Thorpe Park Pass for just £4 more then I did twelve years ago.
Just shows how strong the value of the Merlin Annual Pass really is.
