Memory maker question

[ky.]

Does memory maker need to be purchased at the same time as tickets, or can I purchase it later? I know it has to be done at least 3 days before our trip (not until October), but can I buy our ticket now (with the canadian discount) and then add on the memory maker closer to our trip?

Yes, you can add it later.

You can even purchase it after your trip, but it costs more.
