Well here's a thought what about Universal, then, they own would both sides of international drive which is their ultimate goal I think since they own Wet'n Wild already and much of I drive in that area and they own the land just south of their own property near Lockheed Martin and the convention center so it would make more sense for them to buy it Then they could give Disney a run for their money.
Then Universal could really compete with the Mouse in Orlando. Besides it makes sense they already partner with Sea World , The Kennedy Space Center and several other parks with what is called a flex ticket to try to get Disney guests away from Disney.
Disney has always tried to keep their customers on property as long as possible that's the real reason for the four theme parks on property DHS (Disney's Hollywood Studious and Animal Kingdom where both built for that purpose.
I say bring it on I think it would be great for Orlando's economy and our tourism industry. It would force Disney into thinking of a new park to add to keep guests coming back besides it would be great for jobs. Besides Six Flags doesn't want to come here anyway they are scared of this market or they would have been here a long time ago like rumors have suggested for a long time now .
By the way manta is great they been working on it for a while it's alot bigger than people can imagine
