Seriously, if the really wanted to draw more people in. Add more attractions to the expansion pads that already exits or create new pads, fill those damn empty buildings that once housed some really nice attractions, lower the admission fee, get rid of the god awful Genie+ and Lightening Lane, lower the park hopper fee to make it easier for people to leave an overcrowded park and go to one of the others, Stop building new hotels and allow the area just off property to thrive letting more people with budget concerns have the opportunity to visit the parks without having to take out a second mortgage.
They are still riding on the coattails of a guy that has been dead for 56 years. That piece of material has started to get pretty threadbare as we are now into the third or forth generation of people that never heard of Walt Disney.
They have done everything that would have killed any other business by increasing the number of people that are going to be just one and done and faced so much frustration that they will never return. They have also made the situation a job instead of an adventure. For many of us once very loyal and addicted people that find the whole thing currently not worth the effort needed. Or the cost for not having anywhere near the fun experience we once were afforded.
