Hey there Ante,
Welcome to planDisney and thank you so much for your question! How exciting that your trip to the Disneyland Resort is coming up in just a few short weeks!
By the way you phrased your question, it sounds like you might've purchased a vacation package where the hotel and
theme park tickets were bundled together. If that's the case, then that's likely why it didn't have the option for additional days for your tickets.
Typically, you're able to upgrade your theme park tickets as long as the new ticket option is equal or greater in value. However, I do want to give all the caveats here that I'm not able to see the specifics of your vacation details, so I can't say with 100% certainty.
My recommendation would be to
call a Cast Member at the Tickets line! They are incredibly friendly and knowledgeable and should be able to see the details of what you booked and walk you through any of your available options.
A quick reminder that if you booked a stay at one of the
hotels of the Disneyland Resort, then make sure to take advantage of
Early Entry each morning of your hotel reservation! An extra 30 minutes might not sound like a lot, but you really are able to fit in so much during that time since the crowds are so light.
On a recent trip with my son, we were able to get all of the available Fantasyland attractions in! This freed us up to grab a quick breakfast at
Red Rose Taverne while we waited for our
Lightning Lane return time at
Haunted Mansion Holiday. Such a great start to a morning!
Thanks again for your question, Ante! I hope you have a fantastic time on your upcoming vacation.
Have a Magical Day,
Greg
