Grad Nite allows high school seniors to enjoy a late night after-hours party in Disney California Adventure!
Dates for 2019 include May 10, 11, 17, 18, 21, 22, 28, 29, 31, June 4, 5, 7, 8, 11, 12 and 14, for a total of 16 nights. This year’s Grad Nite ran for 18 nights.
For 2018, the Disneyland Resort switched to a tiered ticket option, with schools choosing between the party only, the party plus daytime admission to California Adventure, or the party plus daytime admission to both parks. This appears to be the model for 2019 as well.
Pricing and registration information will be announced in the fall.
