Hi there Alessandra,
Welcome to planDisney and thank you for your question! I'm thrilled to hear that you're planning a trip to the Happiest Place on Earth during the
Halloween season in early October - it's one of my favorite times to visit.
It sounds like you're having some trouble making your
theme park reservations for your upcoming trip. Since you mentioned the 3-day theme park tickets with the park hopper option, I'm wondering if you mean the
3-day ticket offer that's been available over summer? If so, these limited-time promotional tickets are valid now through September 26, 2024, which would explain why you didn't see reservations in early October.
When looking at the
Theme Park Reservation Availability Calendar for standard multi-day theme park tickets, it does look like both parks still have availability throughout the month of October. So if it is the case that you purchased the promotional tickets then you could either plan a visit before their expiration date on September 26, or you could
call a Cast Member a the Tickets line to see if you can upgrade them to standard 3-day tickets and pay the difference if you'd like to keep that October 3 arrival date.
I hope that helps, Alessandra! Thanks again for your question and have a wonderful time visiting the Disneyland Resort in a few months.
Have a Magical Day,
Greg
