Decorations and Concessions are now sorted into a number of different categories. Zone Thrill Level goals will require you to place a certain number of these different types of buildings.

The icons next to the Thrill Level requirements correspond to the type of building needed, and can also be seen next to any building you have stored.

These are the categories for the different buildings:

Decorations: Amenity, Greenery, Scenery, Monument, Trophy

Concessions: Food, Drink, Headwear, Souvenir
