When I went on the tour of world showcase, the tour guide told us each individual nation's pavillion is funded by private companies from that nation (with the exception of Morocco that was funded by the King). They said that is why those particular nations are represented, it's who is willing to pay to build a pavillion. I don't understand why Disney doesn't try to build new nations. The guide said they had room for a lot more pavillions (I forget how many, but it was a lot more than I thought it would be). If you could pick, what new nations would you add to Epcot? I would add India and Russia. They have very unique cultures, unique architecture and landmarks to incorporate into the pavillions, and unique restaurant opportunities. They could even build a "sleigh ride" for Russia! How cool! What would you add?
