Hello Jeanne! Welcome to planDisney. Thank you for stopping by with your reservation question. I know the reservation system can be tricky, so let's see if we can't get your reservations secured.
I have to say I am not quite sure why the reservation system was allowing you to reserve for the adult tickets, but not when you added the ticket for a child under 10. We do not have any insider information on how the reservation system works, so somehow when you were checking reservations that third ticket was hitting a ticket limit for that day. I do know that the
Theme Park Ticket Reservation Availability Calendar is fluid, so while that may have happened one day it could look different when you check another day. I always tell Guests to just keep checking. I actually just took a look and it looks like at the time of writing this there is availability for Disneyland Park for your three tickets. The calendar will constantly change as people book and cancel tickets, so again. Just keep checking! I am hopeful that you will be able to get your tickets reserved.
If you keep having issues with that third ticket, I think it would be a good idea to give
Ticket Services a call and speak to a Cast Member. The only other issue I could think of is that for some reason, the third (under 10) ticket could be a different tiered ticket than your other two.
Once you get your reservations confirmed be sure to check out
Disney Parks Blog. All of the new and exciting announcements drop here, like the recently announced
return of nighttime spectaculars. You will have to make sure you are able to see some of this entertainment when you visit.
Jeanne, thanks again for stopping by. Be sure to come back and visit us again if you have any other planning questions!
