answer:I haven’t been in 6ish years so this info may be dated… But…. Universal is not nearly as extensive or large as Disney. Don’t get me wrong, both of their parks are awesome, and you’ll still need a full day to experience either… But in my experience, I finished both parks, in one day (each), to my hearts content…. without really using any free pass or special stuff. It may make it go a bit smoother though. The rides at Island of Adventure are the best combination/set in Orlando. I didn’t like Studios as much, but it’s much more similar to the Disney parks in that it derives largely from movies and stuff. Studios also takes longer in my experience.
