It's rare for a resort to be based on a true story. Usually, they're the result of creative imagination and planning to meet the demands of the tourism industry.
I don't think so. Usually, resorts are developed with a focus on providing a fantasy or idealized setting, not necessarily rooted in actual true stories. They aim to attract visitors with their charm and amenities rather than any factual basis.
The movie The Resort is not based on a true story. It's a work of fiction crafted by the writers' imagination and creativity. There are no real-life events or people behind it.
