Hi Jessica,
Greetings from a fellow mom of five! I hope you're having fun planning your Walt Disney World Resort vacation and are counting down the days to all of the magic and fun!
I'm happy to let you know that yes, seating options for
attractions without height restrictions are quite flexible, allowing for families of all sizes with Mouseketeers of all ages to enjoy them together. These rides utilize a bench-style seat, so you should have no problem having two toddlers and an adult ride together. In fact, some attractions will have seats that will comfortably fit even more of you, so your entire family may fit in two or three rows.
For attractions with a height restriction, seating is sometimes a bit more inflexible due to making sure all the Guests enjoy the rides safely. Guests under the age of 7 always need to be with another Guest who is 14 or older. Depending on the ages of your Mouseketeers, if you have any questions about how to make that work for your family, feel free to ask a Cast Member at the attraction entrance if it's okay for your kiddos to be right in front or behind you. Also, are you aware that there's a wonderful
Rider Switch service available if there's an attraction some of your Mouseketeers aren't tall enough for or aren't quite ready to ride? It will allow your family to take turns without needing to wait in the standby line twice!
Thanks so much for visiting us at the Disney Parks Moms Panel, Jessica, and please let us know if you have any other questions as you're planning your trip. I hope that you and your entire family have a truly magical vacation!
Missy
