Ghoulish Greetings, Erika!
Welcome to planDisney. Thank you for sending us your spook-tacular question about
Disney After Hours Boo Bash.
Erika, Disney After Hours Boo Bash takes place after Magic Kingdom Park has officially closed for the day. It is a separately ticketed event and even if you have a standard Walt Disney World Resort theme park ticket or a theme park ticket with Park Hopper Option for the same day, you will need a separate Disney After Hours Boo Bash ticket to enjoy the event.
However, if you wish to save some money, you do not need a theme park ticket to enter Magic Kingdom Park for Disney After Hours Boo Bash. In fact, Disney After Hours Boo Bash ticket-holders can enter Magic Kingdom Park as early as 7:00 p.m. on the valid date of their ticket. This gives Disney After Hours Boo Bash ticket-holders even more time to enjoy Magic Kingdom Park before the event officially starts.
Erika, I hope I have helped answer your question. If you have any other questions, please visit planDisney again. We are always hEAR to help you!
Wishing you a BOO-tiful Vacation,
Priscila
