We're a family of five so we usually have to split up 1 adult 2 children and 1 adult 1 child. We've done this on Splash Mountain, Big Thunder Mountain RR, Pooh, Peter Pan, Buzz Lightyear, River Ride in Mexico, Norway Ride, Astro Orbiter etc. The only one that I can think of that we couldn't was Goofy Rollercoaster.
