If I were to design my own private island, I would include the following. I would build a very large house with as many game consoles, computers, and 4k TVs as it would hold. I would have my own ice cream shop along with my own candy store. The would be a swimming pool with an attached hot tub. I would furnish the house the best furniture i could buy along with posters and collectables from movies and video games. I would have my own private library with as many books as I could read. Given the resources, i would also put dinosaurs on the island so i could have my very own jurassic park.
