Hi Sarah!
It's true that Doc McStuffins and Sofia the First are regularly available for hugs and pictures along Hollywood Boulevard inside the
Disney California Adventure Park.
If your 16 month old loves them, I would encourage you to upgrade to Park Hopper tickets and visit both Parks on the same day of your visit to the
Disneyland Resort!
Plus, if you'll be visiting after May 26, 2017 you will have an opportunity to see the all new "
Disney Junior Dance Party Live Show" inside California Adventure which promises to be super fun for the little ones!
Now, if you're unable to upgrade your tickets, remember there's plenty of Magic to be enjoyed at
Disneyland and amazing characters that you can only encounter there too, like Moana and Winnie the Pooh!
For exact character meet and greet times, make sure you download the
Disneyland Mobile App.
Finally, you can always find wonderful Disney gifts, including the cutest Sofia the First merchandise at
World of Disney in the Downtown Disney District. That may be something to consider to end your visit to the Happiest Place on Earth with a souvenir your little one will love.
I hope this helps.
Thanks for visiting the Disney Parks Moms Panel!
