I suppose it's possible they're all combined? We've never really seen anyone travel between them. Portals would still work since you can use them to travel to Agrabah/Arendelle/Camelot from the Enchanted Forest. So there's always the chance. But I kind of doubt it.

I do think the entire world is included. Hopefully, when we inevitably see Tiana, they can confirm this for us.
