Hi Marie! Thanks for bringing your question to planDisney.
Your Disneyland Resort
admission ticket says you have one day remaining, because you have one unused day left to use on your ticket. A wholly unused one-day ticket will say there is one day remaining, and a multi-day ticket will say there is one day remaining when the other days on the ticket have already been used. I hope this helps!
When is your
theme park reservation? When you selected your preferred day and park at the time of purchase, you made a theme park reservation. Check on your reservation or modify it to another eligible and available day and park by visiting the Disneyland Resort website, hovering over the "My Disneyland" menu, and select "Theme Park Reservations."
When your park day is approaching, check out the
Daily Event Calendar. This is a great place to put together a plan for the day with details on fireworks, parades, entertainment, and more. Details are subject to change.
Have a magical day!
Elizabeth
