Hey there Yesenia,
Welcome to planDisney and thanks so much for your question. It sounds like you're planning a visit for a big group - how fun!
When purchasing
theme park tickets through the Disneyland Resort website, you can purchase up to 15 tickets per transaction with a maximum of 10 tickets for aged Guests 10+. The rest of the tickets (up to 15) can be for Guests aged 3-9. Therefore, if you are trying to purchase more than 10 tickets for Guests in your party who are over the age of 10, then you would need to purchase them in multiple transactions.
However, since tickets purchased on the Disneyland Resort website are tied to your MyDisney account, you'll be able to easily access them after purchase even if they are split over multiple transactions.
If you are wanting to discuss more in-depth about ticket options then you could always
reach out to a Cast Member at the Tickets line. They'll be able to speak to the specific details of your situation and let you know what's available.
Additionally, since it looks like you're planning a visit for early May, did you see the recent
Disney Parks Blog article covering all the fun Star Wars merch deploying across the parks around that time? It's sure to cause a disturbance in the Force for any Star Wars fans in your crew.
Thanks again for your question, Yesenia! I hope you and your group have a fun time making new magical memories at the Happiest Place on Earth.
Have a Magical Day,
Greg
