Hi there Danni-Elle,
I’m thrilled you are headed to the Disneyland Resort to enjoy Halloween Time - it is sure to be a spook-tacular time!
With a 3-Day Park Hopper Ticket, you have the choice to enjoy both Disneyland Park and Disney California Adventure Park on the same day. Sometimes we hop between both parks a few times a day! Guests can exit either park at any time. If you would like to exit and wish to visit either park that same day, be sure to get a hand stamp from a Cast Member at the exit. When you wish to return to a park, you will use your theme park ticket and the Cast Member will check for the hand stamp for re-entry.
Since you are attending
Mickey’s Halloween Party, you will be able to enter Disneyland Park up to 3 hours prior to the party starting with your special event ticket. By having that 3 hour window prior to the event, you may want to take the morning relaxing at your hotel or enjoy some time in the Downtown Disney District before you get in your costume and attend the party. By doing this, you can save one of your Park Hopper tickets for another day but still enjoy hours in the park using only your Special Event ticket.
I hope this helps. Please feel free to write us back if you have any more questions.
Wishing you 999 Happy Haunts!
~ Lynette
