Honestly, I classify the park more to this as of now (excluding Parisian, French, and Baker).
Upper Lot: Universal Blvd (DreamWorks Theater, Universal Plaza, WaterWorld, The Walking Dead Attraction), Minion Way (Minion Mayhem & Super Silly Fun Land), Springfield USA (The Simpsons Ride & Downtown Springfield), Studio Plaza (Universal Studio Tour), Production Central (Animal Actors/SES), Hogsmeade (FJ, Hippogriff, Ollivanders)
The Lower Lot, has no sense of identity; at all (at-least as of now), as I would hope that they would go through the effort of trying to be more cohesive.
