As other people have said Disney and Universal are 2 totally different places.Universal Studio s Island of Adventures has far more roller coasters than any Disney Park, but it is not on Disney Property.The park on Disney Property that has the most roller coasters would have to be Magic Kingdom.Hope this helps!!!
Universal Studios and Disney are two different places. But, Universal Studios has more rollercoasters than Disney does. In the Disney parks, Magic Kingdom has the most rollarcoasters.
