Hey there, Jacqueline! I'm so happy to welcome you to planDisney! We love helping our fellow Guests plan their most magical memories at Disney Destinations.
I'm not aware of any current ticket offers specifically for half-day admission to the Disneyland Resort theme parks. At the moment, Guests may purchase 1-day tickets which are priced by tier, depending on the date selected for their visit. Or, you may purchase multi-day tickets which have a fixed price, regardless of which dates you choose to visit. No matter which ticket type you select, don't forget that you need both a valid admission ticket or pass and a park reservation to enter a Disneyland Resort theme park.
Jacqueline, I want to thank you and any members of your group who are first responders for all you do to keep our communities healthy and safe! Currently, it doesn't look like there are any special offers for first responders, but you may wish to review the special ticket and hotel offers available on the Offers and Discounts Page. These can change periodically throughout the year, so you never know when a great special offer will become available!
Another great opportunity to build savings into your Disneyland Resort visit is to book a vacation package, which includes your hotel stay at one of the three Disneyland Resort hotels or a Good Neighbor Hotel, as well as your theme park tickets, and a few Magical Extras (including discounts on select dining locations and merchandise!)
I hope this is a helpful start, Jacqueline. Don't forget to check out the newly re-imagined Mickey's Toontown while you are here. It's just pure fun and nostalgic delight! If we can help with any other tips, tricks, and heartfelt advice, please come back and see us again, here at planDisney!
Wishing you Wondrous Journeys,
Tishra
