Hi, Melinda!
I’m so excited to read your
question, because I’m also going to be attending
Disneyland After Dark: 90s Nite! It sounds like it’s going to be a night to remember!
That’s a great question!
Anaheim Resort Transportation (ART), the convenient shuttle service option, typically begins service one hour before the Disneyland Resort opens, and continues service until 30 minutes after close. Disneyland Resort hasn’t posted
hours for March 7,
2019 yet, but should post them by the end of next week. (The monthly calendars updated about six weeks in advance). I called ART to find out if they will have a special schedule for that evening. Currently, they don’t have extended hours planned, but they're looking into it. So, more information should be available soon. I'm sorry I don’t have a definitive answer for you just yet! If you’re able to contact ART in one or two weeks, they may have an answer. Or, feel free to reach out to me here and I’d be happy to follow-up.
You can also look into taxi or rideshare service -- there are
designated Guest pickup/drop-off spots off Harbor Boulevard and the Downtown Disney District.
I hope you have the time of your life reliving the 90s!
Kristin
