Hiya Yadira, welcome to planDisney, thanks for your question today.
I am so sorry to hear your son was recently hospitalized, I hope he heals quickly! As
Oogie Boogie Bash at Disney's California Adventure Park is a
seasonal event, unfortunately, Yadira it is non-refundable and non-transferable. If you would like to speak to a Cast Member regarding why you couldn't attend, I would call the
Tickets office at (714) 781-4636 and see what they can do.
Yadira, I am so sorry that I had to deliver some not-so-magical news today. We hope your son continues to heal, and we look forward to seeing you enjoy the magic at Disneyland Resort very soon!
Frances
