The problem with uni is that its already stale. I can't fit on the new harry potter ride in Hogwarts. The want shop was poorly designed and takes ages to get in , dueling dragons was just renamed.
From the late 80s to the early 90s I think the only ride that still exists at universal is ET , I believe everything else has been replaced at this point . So while its nice to get new rides nothing sticks around and sometimes you get a great experience like the mummy and sometimes you get twister.
Disney is able to keep updating classics while building new stuff. Like I said Disney added to magic kingdom , has animal kingdom getting a big make over with avatar and other changes , you also capacity increases at Hollywood and Epcot . We also have d23 in few months .
While I agree that running through some parks in less than a day isn't ideal , I go twice a year , my gf and I go without my nice and nephew once a year. There is no reason when we are alone to sit through beauty and the best , little mermaid and Disney junior. So we do rocking roller coaster , tower , indie , star towers , Muppets and the great movie ride. Sometimes we are done before lunch so we sit and eat lunch and then hop over to animal kingdom and do the safari , Everest , Dino and a couple of the trails and end with dinner and go home .
With universal I can do the same by buying a fast pass. I can do both parks in a single day and enjoy everything I wanted to enjoy have a great lunch and dinner and be out and on the way home. But after that there is no reason to go back , at least at Disney I till have Epcot nd magic kingdom
