Disneyland Buenos Aires combines many Latin American, Brazilian, and other cultures.
The "Main Street" type entryway would have shops lined up like a Latin American/Amazonian villiage and have a parade similar to ¡Viva Navidad! at Disney's California Adventure
As you enter Disneyland Buenos Aires: As you cross a giant bridge, the Jungle Cruise will be flowing below you, Adventureland will be on your left, Critter Country (with Splash Mountain) will be on your right, and jungle/rainforest plants will surround you
As you can see Disneyland Bueons Aires will include Adventureland, Critter Country, Fantasyland, Tomorrowland, and a land similar to Frontierland (Big Thunder Mountain Railroad pictured)
The Entrance will have the Jungle Cruise flowing under the large bridge to enter the rest of the park
