Come again and again...
With an LEGO® House Annual Pass, you can come as often as you like. The price for an Annual Pass is 399 DKK, and you are already saving money from your second visit.
The Annual Pass can only be purchased by personal inquiry in the Information at LEGO House. If you want to get your ticket upgraded to an Annual Pass, you can do it all day the day your ticket is valid (your ticket of the day is refundable upon purchase of the Annual Pass).
The Annual Pass is valid one year from the date of purchase.
