Hello, Cassy! Thanks for bringing your question to the Disney Parks Moms Panel.
I'm not aware of any future promotions at this time, but the
current promotion for Canadian residents is a great deal! You can explore the Disneyland Resort for three or more days and you have until February 28, 2017, to purchase. As you mentioned, these tickets do expire, so the first use must occur by December 31, 2017. Also, keep in mind that proof of residency is required, so each ticket holder must show a valid Canadian passport or NEXUS card upon entrance.
I do hope you are able to take advantage of this great offer this year. With a three-day or longer ticket, you are entitled to one
Magic Morning at Disneyland Park. This extra hour is really valuable as I find you can get a lot done early in the morning.
Please stop by the Disney Parks Moms Panel again if you have any other questions!
