Hi Andrea,
Welcome to the Moms Panel!
I love that you are planning ahead for your first trip because it will be here before you know it!
The Power Rangers are no longer appearing anywhere at Disney World. They made their last appearance at Disney's Hollywood Studios (DHS) in August of 2010.
However, there are tons of awesome characters that do meet and greets at Disney World. Some of the super cool recent additions include Phineas and Ferb at Disney's Hollywood Studios.
The
Disney Parks Blog announced on 7-19-2011 that Lightning McQueen is now appearing in the
Lights, Motors, Action! Extreme Stunt Show.
Although they can't sign autographs, Guests can pose for pictures with Lightning McQueen and Tow Mater at the Team McQueen Headquarters near Streets of America and Muppet*Vision 3-D.
Please let us know if there are any other characters or special experiences your sons may be interested in and we'll be happy to assist you.
Wishing you minnie magical memories :-) Allison
