Isadora Artiñán’s family net worth

Isadora's family net worth has been widely debated and i've seen various different opinions on what it might be so i decided to give it a go myself. Isadora and her family are supposed to be based of Paris Hilton and her family and the Hilton's are worth $14 billion now The Artiñán's own a hotel chain across europe and south america and to build and average individual hotel would cost around 40mil plus so the fact that they have multiple of those around the world also bringing them in money would give them quite a lot of cash and they own many clubs and to build a club would be around $2-5 million depending on how exclusive it is. In Isadora's opening scene we see her coming out of a helicopter which would cost them about 1million which would mean they would need to have a high net worth to afford these things so i would out they're net worth at minimum $300million and maximum $700 million and maybe a bit specifically around $500 million. Many people would say this is an overestimation but giving that they're hotel chain is the biggest source of income and it takes around $50 million to build one they would only need ten hotels to be worth half a billion dollars and i'm pretty sure they have more than just ten hotels. lemme know what you think guys, am i wrong?
