The masks are available at the Kidcot station at any country (these will be marked on your map) and are free. Kids can color the masks, and the CM at each country will put a stamp on the mask's stick and hang a little cut-out from that country on the mask.
There are also passport kids, which can be bought in any country for $9.99. I think they're also available in Future World, but I'm not 100% sure. We got ours in Mexico - they were right by the cash registers. In the kit you get a passport with stickers for each country and a button. At the Kidcot station, you can get the CM to sign your passport. They'll use the same stamp as on the mask, and a lot of times they'll write something on there in their language. We did both the masks and the passport and really liked them both.
We did not do the penny presses, but intend to next year.
Here is a site you can go to if you want to see the locations of the machines. I know you can also buy little books to put your squashed pennies into, but I don't know where they're sold. Someone will, though, I'm sure!
