Greetings, Denise! Welcome back to the Disney Parks Moms Panel! In a few years, I’ll have kids in the same situation, so I hope I can help you towards a solution that will work for you and your kids.
After speaking with a Cast Member at
Guest Relations, your best course of action is to take each attraction one at a time. Approach the Cast Member at the beginning of the queue, and ask them if the 10 year old may ride alone (guests at Walt Disney World Resort must be
14 years old to enter the park alone, and over age 7 to ride an attraction by themselves). If the Cast Member says yes to that particular attraction, you and the younger child can go through the queue with him, and not ride.
There are many attractions throughout the
Walt Disney World Resort that all three of you can ride together, so I urge you to take those into consideration and make them the bulk of your trip. Then, if your 10 year old wants to ride Space Mountain, you can follow the above advice. I hope y’all have a wonderful trip! ~ Lindsey P.
