Greetings Luliia!
Thanks for stopping by the Disney Parks Moms Panel! Celebrating your birthday at the Happiest Place on Earth sounds like a fantastic idea. I still haven't had the chance to do this for myself, but it is definitely on my bucket list.
There are a few ways to save money on Disneyland Resort park tickets. If by chance you are a
Southern California resident, you can save on a 2-Day or 3-Day Ticket with this limited time offer. These special tickets are valid January 8 through May 24, 2018, excluding blockout dates March 23 through April 8, 2018. These tickets expire May 24, 2018. Discounts are also available for
military service members and their families if this is applicable to you.
Keep in mind that if visiting the parks for a single day, ticket prices vary by date and season. Just head over to the
Ticket page, select "1" for "Number of Days" visiting, and you can see the prices on the calendar for the potential days you are interested in visiting. You may find a less expensive ticket during the week, for example. Alternatively, if you plan on spending multiple days at the Disneyland Resort, you will save money per day as you increase the number of days of your park ticket (up to 5 days).
For your big day, you must stop by City Hall for your complimentary Birthday button. Don't be surprised if you get some extra special attention wearing it throughout the parks!
Please stop by with any other questions, and have a magical day!
