I want to take my two kids to disneyland while my husband goes hunting in october. I need some advice though. They are 5 and 3. Each is just over 40 inches, so able to go on most rides, including most roller coasters. Can we all ride the two per row rides? Like space mountain. Is it safe to have my older one in the row in front of me while I sit with my younger one? Or have them both in front of me on splash mountain.
