You are so ignorance. It has an amazing backstory:
Once it was aiece of old Florida land, then it became a parkinglot when a magical film company opend a theme park there. People of all over the world came (except narrow minded Disney lovers). Then a other company came and redeveloped it into CityWalk, then another company came and did it better, the end.
I personaly think it beats the bs of the Disney Springs back story.
Skull island is an Island. It says so in the title, get over it.
You two could always find a middle ground and call it a peninsula.
