There are many other more interesting places than Poland to visit. Even Prague in the Czech Republic 'knocks the socks off' anything in Poland.
Hmmmm maybe I cut you a bit too much slack Michal ;)
Firstly don't be so stunned that someone expresses a desire to visit Poland. This is a Polish forum so it's inevitable that people who have an interest in the country will gravitate to forums such as these.
Secondly, your statement that Prague "knocks the socks off" anything in Poland is a very simplistic thing to say.
To see Poland at it's best then go in the summer. Yes it can be unbelievably hot but you won't be going there to work but to have a vacation. In other words you can take it easy and enjoy the weather (and all the beautiful girls in their summer outfits ;) )
Poland has something for everyone. Mountains, lakes, forests, history, culture breaks, unspoilt seaside resorts.
Whereas Prague has wonderful architecture, cheap beer and lager louts......no contest !
