Hey there Gordon,
Welcome to planDisney and thank you for your question! I'm happy to hear that you'll be taking advantage of the wonderful
3-Day Disneyland Ticket Offer for your upcoming trip.
With the base version of these promotional tickets, the thing to keep in mind is that you're able to visit the parks from Monday to Thursday, but they are not valid for admission from Fridays to Sundays.
However, if you pay a bit more then you can purchase the version of this ticket with no blockout dates so you would be able to visit any day (Monday to Sunday) as long as there are available
theme park reservations for each day you plan to visit.
If you've already purchased the base version of these tickets then I'd recommend
calling a Cast Member at the tickets line to see if you'd be able to upgrade to the version with no blockout dates and pay the difference! That way you can visit on the two dates you mentioned. In case you're not able to see the page I linked, that phone is +1 (714) 781-4636.
Additionally, make sure to check out the
Disney Parks Blog for a glimpse into all the fun things happening around the Happiest Place on Earth during your visit! I especially love the
Foodie Guide for all the seasonal food and beverage options offered during the Halloween season.
Thanks again for your question, Gordon! I hope you have a fantastic visit to the Disneyland Resort in a few weeks.
Have a Magical Day,
Greg
