Welcome to planDisney, Bridgitte! Thanks for stopping by with this question.
You are able to purchase
tickets for same-day entry at the Guest Services window, located in the Esplanade to the left of the Disneyland Park Main Gate. However, although you may be able to purchase a theme park ticket, you will still need a
park reservation to enter on the same day. I would recommend purchasing your
ticket online so you can be sure that theme park reservations are available.
Bridgitte, I took a look at the theme park reservation calendar for today and currently, park reservations are not available. I would recommend checking back to see if they may open up later in the day. The easiest way to check would be to use the
Disneyland app. On the app, you can not only see if any reservations are available, but also purchase your tickets and make reservations if any pop up.
If your plans are flexible, the theme park reservation calendar does currently show availability for the rest of the week, excluding Friday, September 25. This may be a good alternative as Halloween Time at the Disneyland Resort is especially popular. With fan favorites like Haunted Mansion Holiday and Guardians of the Galaxy - Monsters After Dark returning, a lot of guests prioritize visiting during this season!
Bridgitte, I hope this information helps you as you look to visit the Disneyland Resort. If you have any additional questions, please visit us here again at planDisney!
Happy (early) Halloween!
David
