Hey there Priscilla,
Welcome to planDisney and thank you for your question! What an amazing and memorable 6th birthday celebration you're planning for your daughter! It will be so fun to celebrate her at the Happiest Place on Earth.
When it comes to
group visits to the Disneyland Resort, specially priced tickets can be offered through
Disney Imagination Campus, for educational field trips, and
Disney Meetings & Events team, for things like conventions and other events.
If you're looking for discounts for a larger group that is visiting, then my recommendation is to check the
Special Offers & Discounts page to see if any of those promotions might apply to your situation. There are typically different discounts offered throughout the year on this page, so it's a good one to bookmark.
Since it will be your daughter's birthday, you'll also want to make sure to pick up a
complimentary birthday button so she can be celebrated all around the parks! You could also consider an in-room celebration and/or a fun character dining experience during your trip as well.
Thank you again for your question, Priscilla! I hope you have fun as you continue to plan and make sure to come back and see us if you think of any follow up questions.
Have a Magical Day,
Greg
