First of all, don't panic. All you need to do is visit your issuing attraction. The admissions team will look you up on the system and print you off a new card. Please note that an administration fee of $10 applies for each card reprinted. You will need to bring with you a form of photographic ID. Please note the fee is waived if a pass has been stolen, with proper documentation.
If you are unable to visit the issuing attraction, please email LLF.Experience@LEGOLAND.com
