Greetings, Wendy!
Thanks for stopping by the Disney Parks Moms Panel with your great question. I also happen to have a very big fan of Vamparina in my household, and meeting her was on our list of must-do's on our last trip. I'd love to give you some tips to help increase your chances of meeting this "ghoulish girl in a human world."
While Character appearances are always subject to change, your best chance of seeing Vamparina is in Hollywood Land in Disney California Adventure Park. Make sure you check the official
Disneyland app each day for a list of Character appearance schedules and locations. If Vamparina is meeting Guests, you will see her listed in the app. On our last trip, she only was visiting on certain days so make sure you check every day and meet her right away when you can as she may not be appearing the following day. Don't forget your cameras and autograph books!
If your child is also a fan of other Disney Junior Characters, they must check out the
Disney Junior Dance Party in Disney California Adventure Park. Here they can dance and play to fun familiar songs with these Characters. My son loves the falling confetti during this party and usually wants to experience it more than once on our trips.
I hope this helps, and please return if you have any other questions. I hope your trip is spooktacular!
