The preview days for annual pass holders at both Thorpe Park and Legoland will not be making a return in 2012.
Chessington World of Adventures will still hold a preview event, which will be extended over two days and restricted to annual pass holders only.
The preview events at all three parks in March last year reached capacity, with Thorpe Park in particular struggling to cope with the demand on catering and for the rides.
The Chessington event will take place on the weekend of 17/18 March and be pre-booked entry only.
