I have a pre-opening brochure from Epcot Center which was sent to me from the Magic Kingdom Club (now Disney Club). It says in there that Coming- World Showcase: Israel, Equatorial Africa, and Spain. Since I don't have a scanner, I'll simply type what it says for each country.
Israel - The Menorah, symbol of the State of Israel, stands at a courtyard center, surrounded by buildings reflecting the rich balance of new and old. Walk through ancient Jerusalem to an amphitheater to hear performances of both classical and folk music. Sample native dishes under the shade of olice and cypress trees in the Israel pavillion.
Equatorial Africa - The Equatorial Africa pavilion takes you on safari through a world of natural beauty and adventure. You'll feel the electrifying energy of the "Heartbeat of Africa" show and sway to the jungle beat of the music and dance. Alex Haley, noted author of "Roots", is your host for "Africa Rediscovered", an adventure uncovering Africa's ancient cultural heritage.
Spain - Take a spectacular journey through Spain by film to little know and out-of-the-way vacation Edens. A ride attraction captures the country's passionate heritage and spirit in her arts. In a waterside restaurant, indulge in tapas, or Spanish-style finger food - a blend of varied ingredients but suitable to simple tastes. And browse the market places of striking contrast, from pueblo village to aristocratic opulence.
After thinking, I realized that Equatorial Africa is Morocco, so that leaves only the other two.
Also, keep in mind that this was published in 1981 or 82, so it was a very early vision.
