Well, if you are asking for a comparison between EPCOT’s innoventions and DLR’s version, then there is no question that EPCOT’s is NO COMPARISON! EPCOT’s Innoventions span several buildings. There are showcases for the latest technologies, demonstrations, games, shows, and much much more. The cheap ripoff they tried to stuff into the old CoP at DL pales in comparison.
Now, the question of if you should visit is another matter. EPCOT is HUGE anyway. There is so much to see and do already that innoventions tends to go to the bottom of our list. Does that mean it’s bad, certainly not. It just depends on several factors, like how much time you have in your day, what the wheather is like, and what your interest really are. Is it worth checking out - yes, is it a can’t miss - no, is it better than the DL version - without question.
