I hope I'm not stepping on your toes, twotoohappy, but I wanted to offer a couple of notes more appropriate for the adults and older kids who are really interested in other cultures. Thank you for going to the effort of putting all this down.

Mexico:
Hello = Hola [oh-lah]
Thank you very much = Muchas gracias [moo-chahs grah-see-ahs]
Good-bye = Adiós [ah-dee-ohs] or Hasta la vista [ahs-tah lah vees-tah]
You can greet someone by saying "Como estas?" (coh-moh ess-tahss), meaning "How are you?", and if they ask you, you can say "Muy bien, gracias"(Mwee bee-en, grah-see-ahss), or "Very good, thanks".

China:
Hello = Ni hao [ nee how]
Thank you = Xiéxie [shay-shay]
Good-bye = Zai jien [sigh jee-ahn]
Maybe it's a different dialect, but I think in Mandarin thank you is usually pronounced more like sh(y)eh-sh(y)eh, where it pretty much sounds like sheh, but there's a tiny "yuh" sound in there.

Japan:
Good morning = Ohaiyo gozaimasu [oh-hì-yoh goh-zì-mahs]
Good afternoon = Konnichi wa [ kohn-nee-chee wah]
Good evening = Konban wa [ kohn-bahn wah]
Thank you = Arigato gozaimasu [ah-rr-gah-toh goh-zì-mahs]
Although just knowing any Japanese is probably enough, in Japan a customer would probably not use gozaimasu to a server. It's a more polite form, and while in Japan a server might use it with a customer, they would probably be embarassed if a customer used it towards them. I would use "ohayo" for a greeting, and "domo" (doh-moh) for thank you. Domo is technically "very", but the phrase "domo arigato" is often shortened to domo. If you want to be effusively, knee-bendingly grateful, like a CM found your baby about to crawl off a ledge and saved her/him, you can say arigato gozaimasheeta(goh-zayee-mah-shee-tah), which is about as polite as you can get.

Morocco:
Hello = salam alekoum [sah-lahm ah-lee-cohm]
Thank you = baraka llahu fik [bah-rah-kah lah-hoo feek]
Good-bye = llah ihennik [lah ee-hen-neek]
If someone says salaam aleikum to you first, you should reply aleikum salaam. Just reverse the words.
I hope this makes your conversations in Epcot a little more fun! Thanks again to twotoohappy for doing most of the work first!
