As long as your voucher or coupon states that it is valid for LEGOLAND® Discovery Centre Melbourne we will accept it for entry into the attraction. However the terms and conditions for each voucher can vary, and therefore would recommend reading the terms and conditions of the voucher before visiting the attraction.
Generally 2 for 1 vouchers and discount coupons can only be redeemed on the day of your visit, when presenting the voucher at the admission desk and purchasing a full priced adult ticket to redeem the second ticket for free. They therefore cannot be used in conjunction with Annual Passes, pre-purchased tickets or any other offer.
