Hi Luis, welcome to planDisney!
I'll do my best to help! It sounds like you already purchased a
one-day theme park ticket, and are trying to book a
theme park reservation, but all Saturdays are showing as not available. I just checked the
Theme Park Reservation Availability Calendar and most Saturdays actually show as being available to book, so I think I might know what's going on.
The
Disneyland Resort uses a
ticketing tier system for standard one-day theme park tickets. This means the price of the ticket will vary depending on the theme park reservation date that you select. Tickets currently range from Tier 1 to Tier 6. Tier 1 has the most restrictions in terms of eligible reservation dates and Tier 6 has the least number of restrictions. The ticket that you purchase will be valid for admission on the date you selected and on dates in the same or lower tier. Peak demand days, like holidays and weekends, are typically higher tier days.
I think you might have purchased a one-day theme park ticket that is a lower tier, which is why Saturdays show up as unavailable to book. But no worries this is an easy fix! I see you are located in California, so if you are able, you can visit the Disneyland Resort Main Entrance Ticket Booths and upgrade your ticket to a higher tier ticket. The amazing Cast Members can certainly help you out! Another option would be to try calling the
Disneyland Resort Ticket Line at 714-781-4636 and see if the Cast Members there can help.
In the meantime, if you have any other questions, you know where to find us!
See ya real soon!
