Any special things I can see while being there?
Well, when you get bored, you can always visit Lublin, it's only about ~50km from Kazimierz. I make this distance by bike every summer, so it's not so far (but there are also buses which can take you to Lublin) :)
Prices are medium high (when comparing to Lublin for example, but like sb said before... Kazimierz it's rather tourists' town so that kind of prices are normal).
Oh, and there is also Naleczow, but I'm not sure if it will be interesting for you, for me it isn't... but I was there so many times so my opinion is subjective.
