I did it way back...truly one fo the best experinces of my life. work can be tedious, but erally, what is not to love talking to people all day either in Food & Bev or Attractions or Merchandise??
You live with people from the other pavilions, in a large complex, similar to the College Program. The International Program is 12 months, and possibly can extend to 15 months, but it's a very specific Visa.
You have to be 18, but we had people anywhere from the 18 up to 30 there during my time. Some are still my best frineds and we tend to travel the world to try and meet up again, even these many years later. My DH has met tons of the other Canadians I worked with and we had a reunion of many from our year from all over a couple of years back.
The flag under their name tag isn't about the country they are from (the pavilion and costume should tell you that)...it denotes another language spoken (like a France flag for French, Italy flag for Italian, etc).
For those thinking of applying...definitely do it! Great year with amazing memories and experience!!
