Hello there Angie, and welcome to planDisney! I see your trip to the
Disneyland Resort is just around the corner, how exciting!
Both of my kids were special guests of Mickey Mouse before their third birthdays, and great news, you do not need to show proof of his age. It is a great question, and one I asked as well before our first visit! As long as every member of your party has a
valid ticket and a
theme park reservation for your dates you'll be visiting the theme parks, you'll be ready to experience the magic!
I highly recommend taking your nephew up to the reimagined
Mickey's Toontown in
Disneyland Park. Not only is the adorable
Mickey & Minnie's Runaway Railway Attraction located there for guests of all ages to enjoy, but it is home to
CenTOONial Park where there are several areas for little Mouseketeers to stretch their legs and play. There is also a great grassy area towards the back of Mickey's Toontown that is a bit quieter if you need a place to relax or have a picnic!
I hope this information was helpful for your trip planning Angie, and don't hesitate to
come back and ask me any other questions leading up to your vacation!
Have a magical day!
Melissa
