Hi, there!
Welcome to planDisney, Elizabeth. I'm so happy you stopped by and even happier to hear you're planning a Walt Disney World Resort vacation! It's the very best kind, if you ask me.
Purchasing
Lightning Lane Multi Pass for your theme park adventures is a great way to minimize your wait times and maximize your fun. Win-win, right? You ask an excellent question about buying Lightning Lane Multi Pass for a little one. If you want the 3-year old to enter a Lightning Lane for a particular attraction, they'll need Lightning Lane Multi Pass to enter with the rest of your group. There are many, many attractions in all four theme parks that are perfectly suited for a little one, like Peter Pan's Flight, Frozen Ever After, Mickey & Minnie's Runaway Railway, and Kilimanjaro Safaris (just to name a few!). I recommend taking some time to review the list of Lightning Lane attractions and experiences in each park. If you see that there are lots of attractions and experiences on that list that your little one would enjoy, I would very much encourage you to include them in your group purchase of Lightning Lane Multi Pass.
Have you heard of
Rider Switch? This family-friendly service is super helpful when you're
visiting the theme parks with a little one in tow. With Rider Switch, your party can take turns riding a popular attraction and waiting with your 3-year old. It's saved my family lots of precious time!
I hope this was helpful, Elizabeth. Please let us know if you have any other questions about your Walt Disney World Resort vacation! We'd love to help you plan a magical stay.
