I've been thinking about this for a while and considered many possible reasons for all the new resort construction . A 5th Park to me seems like the only likely reason for all this new construction . I know Star Wars Galaxies Edge is going to be hugely popular and the reason many will suggest as the primary reason for all this resort expansion ...but I don't believe that it will be popular to the extent that Disney feels they can fill all these new rooms year round because of it . I believe that because of the coming 3rd Park that Universal has planned (though not yet announced) Disney has been planning a multilevel multi-year expansion to combat Universal's aggressive attempts to capture more of Disney's market share . Updating , upgrading , renovating , and expanding all the existing parks at an unprecedented pace shows that Disney is taking Universal's growth as a real threat to their kingdom and will fight back any and all ways to maintain their supremacy in the theme park industry . Building new resorts and a 5th theme park as well seem like another way Disney can and probably will secure their number 1 status in Orlando for the foreseeable future .
