Hi Cynthia!
Thanks for submitting your question to the Disney Parks Moms Panel! The Hollywood and Vine Restaurant is currently featuring Jake the Neverland pirate, June from Disney's Little Einsteins, Handy Manny and Special Agent Oso. Keep in mind that the character experience at Hollywood and Vine is only during breakfast and lunch, not dinner. You can also see Jake and the Neverland Pirates, at Disney Junior - Live on Stage!, also located in Disney's Hollywood Studios.
Here are a couple of "must see attractions" my little ones can't live without: "Toy Story Midway Mania" and “Disney Junior – Live on Stage!” at Disney's Hollywood Studios; "Peter Pan's Flight", "Buzz Lightyear's Space Ranger Spin", "It’s a Small World” and the "Magic Carpets of Aladdin" at the Magic Kingdom, "The Seas with Nemo and Friends" at Epcot and "The Boneyard" play area at Disney's Animal Kingdom! Also, you don't want your little one to miss meeting their favorite characters! Disney Junior characters, including Sofia the First, Doc Mc Stuffins, and Jake can be found at Disney's Hollywood Studios. Mickey Mouse can be found at all of the parks. For a complete list of character experiences and locations, please visit the Character Experiences page.
Hope this helps!
Wishing you a great vacation!
Yael
