At the first country you go to you can pick up a mask for your boy(s). Then at each country, they can stop at the Kidcot table and decorate their masks, adding different details, depending on the country. Young boys should enjoy it -- as long as they enjoy coloring, markers, glue., etc. It's a cute project. And the parents can shop aorund a bit int he same store that has the Kidcot table while their children work on their masks. This is a free and fun thing for kids.
You can also buy an Epcot "passport" that comes with a bunch of stickers and places to get stamped at each country. The mask OR the passport is probably enough, but both are fun. My kids do both and enjoy both.
HTH!
