Not to derail this further, Disney World probably has the only true bubble. It feels like it is away from everything with the forested areas in place. You have to go into the property to get to the parks and hotels. Universal has a semi-bubble with IoA, Citywalk, and Uni Studios, along with Hard Rock, Portofino, and Royal Pacific. Still, it doesn't have the same feel as it is all surrounded by the city. However, this is just my opinion.
Epic Universe and any surrounding areas will probably have another minibubble. So, two mini bubbles with some ancillary hotels/dining.
