Hey Howdy Hey, Deene!
Welcome to planDisney! Thank you so much for galloping by with your question. Deene, I just returned from Disneyland this week and you are in for a frightfully fun treat during your October visit. Both Disneyland Park and Disney California Adventure Park are dressed up in their finest Halloween and fall decor, and there are even special treats you don't even have to do a trick for, characters in costume, and special Halloween Screams fireworks on select nights in Disneyland Park.
Deene, I just double-checked on my end and chatted with a Cast Member in Guest Services. While I don't see the small print you mentioned that says tickets aren't valid on the 2nd and 4th of October, what I did notice is that you can currently
only purchase a single park ticket for Disneyland Park on those two dates.
There are no single-park tickets for
Disney California Adventure currently available for those dates. If you purchase a
Park Hopper, currently you will have the flexibility to visit both parks on those October 2nd and 4th dates. Please note this is true as of now, based on the current availability I saw today. This is of course subject to change, but it's what is available for now, so if you are interested in this option, I would giddy up on over to book it right away.
As a reminder, if you purchase a single park ticket for those dates for
Disneyland Park, you will need to make a
theme park reservation as well as have your valid ticket. You must have a valid ticket before you can make the theme park reservation. Note that if you purchase this option for the dates you selected, you will only be able to visit Disneyland Park on those dates.
If you purchase a Park Hopper ticket, you need to make a
theme park reservation for your
first park, and you must enter the first park before you can park hop to the second park. Park hopping becomes available beginning at 11:00 a.m. on the day you plan to hop. For example, if you make a reservation for Disneyland Park as your first park, you must enter Disneyland Park first (and enjoy all of the fun Disneyland has to offer) and then enter Disney California Adventure any time after 11:00 a.m. on that day. The same is true in reverse if you make the theme park reservation for Disney California Adventure, you must enter that park and then can hop over to Disneyland after 11:00 a.m. Again, this is only if you have a Park Hopper ticket.
Once again, I don't see anything else that says the tickets aren't valid on the 2nd & 4th. But if you continue to see this, I recommend
calling the Ticketing team at Disneyland Resort. They may be able to direct you further.
I hope this helps you, Deene! If you have any further Disneyland planning questions, stop back to see me and I'll round up the answer for you. Remember, shoot for the sky!
Your friend,
Keri
