Each brick may contain 3 lines of script with up to 16 characters per line. Spaces and punctuation are counted as characters. All names must be separated by a space, comma or hyphen. Inscriptions are automatically centered.
Brick inscriptions may include proper person or family names, a single date and a place (such as Anaheim, CA). No other information, including, but not limited to, slogans, titles, memorials, messages, copyright information, company or group names may be included on the brick.
A brick sponsorship is $150 and for an additional $35 you can purchase a 4-inch acrylic or wooden replica of your brick. Please note that although a brick sponsorship will not be taxed, a replica order will be taxed (8.75% tax) if it is being shipped to California or Florida.
Please allow approximately three weeks after your order has been received by our office for the confirmation mailer to be sent via the United States Postal Service. The mailer will include your sales receipt, a Certificate of Authenticity and a map of the walkway. The map will highlight the section of the walkway in which your brick will be installed.
If you choose to order a replica of your sponsored brick, the replica order will ship approximately 10 weeks after you have received the confirmation mailer, barring any unforeseen delays.
Brick sponsorship orders are scheduled to be installed during February 2011, barring unforeseen delays. We encourage you to call our office during or after that time for updates on the latest bricks installed, especially if you are planning on visiting Disneyland Resort to view it.If you should have any questions regarding a brick sponsorship or would like to place an order over the phone, please feel free to contact the Magical Memories office at (800) 760-3566. International Guests may call (714) 781-7557. Cast Members are available to assist you Monday through Friday from 8am to 5pm Pacific Standard Time.
