Hey there C,
Welcome to planDisney and thanks so much for your question! I'm sorry to hear that you've hit a snag in planning for your upcoming trip.
If I'm understanding correctly, it sounds like you've purchased 8 theme park tickets and made theme park reservations for 6 of the 8 tickets. However, when you try to make theme park reservations for the final two tickets, you're getting an error?
If that's correct, one thing you might want to try first is to check the
My Plans hub. This is a really convenient place to make and manage all the different reservations for upcoming trip from one place. I'd be curious if you're able to see your theme park reservations for your upcoming trip on this page and if you can modify them to include the two tickets that were giving you trouble.
If not, then my next suggestion would be to
call a Cast Member at the Tickets line. They'll be able to give you direct guidance based on the specifics of your situation and let you know what your next steps should be.
Also, I wanted to note that you'll be visiting during the Holiday season so make sure to keep an eye on the
Disney Parks Blog as you get closer to your trip to learn more about all the fun that will be happening around the Happiest Place on Earth during your visit. In particular, I'm a huge fan of the "Foodie Guides" which detail all the delicious food and beverage options on offer around the parks.
Thanks again for your question, C! I hope you have a fun trip to the Disneyland Resort in a couple of months.
Have a Magical Day,
Greg
