We are planning on visiting both parks tomorrow 10-06-17 but we do not have a ticket for the special Halloween event. From my understanding disneyland closes at 7 for non-ticket holders but does California adventure close early as well? TIA

California adventure close at 8 during the off season so you can still enjoy the park there after disney closes

Luckily California Adventure still closes later, they do World of Color just prior to closing.

You must have the park hopper ticket though to be able to do two parks in one day.

California Adventure closes at midnight tomorrow, 10/6. As William Smith stated, the lines to get into California Adventure after 7:00pm are horrendous.

California adventure closes at 12, but i would suggest leaving Disneyland before 7 because the line gets very long to get into California Adventure.

California adventure closes at its regular time of 10 tomorrow. Although there are Halloween themed attraction (cars land sunset moment) the main party is only in the Disneyland park after 7 at night
