Hi Suzanne!
My family loved meeting
Moana at Disney's Hollywood Studios and I sure do hope she sticks around! She is currently at
Disney's Hollywood Studios inside the Walt Disney: One Man's Dream exhibit.
Olaf is also at Disney's Hollywood Studios currently.
I haven't heard any official news about the permanency of the character meet-n-greets for either Moana or Olaf at the current time.
However, the characters are always subject to change. There are a few ways to check to see what characters are at the parks during your visit. You can ask a Cast Member at the park to call the character hotline to see what characters are greeting guests in the park that day and the times.
You can also check your
My Disney Experience app to see the characters, greeting times and locations.
When you are in the park you can also pick up a Times Guide, which will have all of the character greeting times and locations listed.
I hope you have a magical vacation!
Magically,
Stacy
