There was certainly a lot less English spoken than elsewhere we went in Poland, so my advice to any foriegners thinking of visiting there is to have at least a few basic Polish words at your disposal (but surely we do that as a courtessy anyway, don't we, foriegners?). The people we spoke to were very friendly...
