Hey Nicole!
Welcome to
planDisney!
I hope you had the most amazing time during the two days you visited the Happiest Place on Earth. Were you able to race down Route 66 on Radiator Springs Racers or hop on a Doom Buggy and tour through all of the Happy Haunts on the Haunted Mansion? It's such a fun time to visit Disneyland Park and Disney California Adventures Park right now with the
Disney100 Celebration Disneyland Resort going on in full swing. There's so much fun, adventure, and Magic right now in the parks.
I see that you purchased a 3-day Park Hopper
Ticket and were only able to use two out of the three days. The expiration date that you see on your tickets of 12/15/2023 would be the expiration date if the ticket was whole and unused. Multi-day tickets must be used within 13 days of first use. Because of that you would have up until the 13th day after you first used the ticket to use the last day on your ticket. Unfortunately, if more than 13 days have lapsed since you first used the ticket then that last day has expired and is no longer valid.
Well Nicole, I hope I was able to answer your question today. Let us know if you need anything else.
Remember, always believe in the Magic!
