Hanna, Rockzmom, thanks a lot. I have sent resume to "http://www.swandolphin.com" 5 minutes ago. Thanks for the links, DisneyLand is interesting for me. I heard something about Alaska and fish companies) It's not "Work and travel" it's only "Work". I'll try to get job offer in DisneyLand.
Also I'll think about
Martha's Vineyard or something like that
. But there are big competition between other students from Russia, Ukraine, Belarus. ..
