Welcome back to the Disney Parks Moms Panel, Adriana. There's no limit to the number of riders per family permitted on an attraction. The only limitation is whether a child is able to meet the minimum height requirement for certain rides.
To go on an attraction, children under 7 years of age need to be accompanied by someone age 14 or older. However, they may sit together on a ride provided that either you or your husband will be on the ride with them as well.
Some of our favorite
attractions where everyone in my family enjoys are Toy Story Midway Mania!, Radiator Springs Racers, Luigi's Rollickin' Roadsters, Autopia, Peter Pan's Flight, and Big Thunder Mountain Railroad. I hope you'll find a few family favorites during your trip!
I hope this information is helpful for you. I wish you and your family a magical time at the Happiest Place on Earth, Adriana. Please visit us on the Panel again if you have further questions.
See you real soon,
Kiki
