Not that these descriptions ever really matter, but I do find it intriguing that the Fantastic Worlds and Epic Universe have different intended uses according to the trademark filings...
Fantastic Worlds
Entertainment services in the nature of amusement park and theme park services; entertainment services in the nature of an amusement park ride; entertainment in the nature of amusement park attractions, namely, a themed area
Epic Universe
Amusement park attraction and theme park services; live stage performances, namely, presentation of live show performances; providing waterpark services; providing recreational areas for entertainment and amusement, namely, interactive play areas
Again, usually these descriptions are kinda just catchalls, but it's interesting that they're different in this case.
