The one thing I really want to know about is visiting Auschwitz. It seems in high season you have to have a guided tour. Do you have any experience with these? How difficult are they to book? I don't know exactly when I will be in Krakow so I don't want to book yet. Other than that, I'm just trying to get a feel for culture from the places I visit. If you have any advice I would greatly appreciate anything you have to offer. My plan is to do a little research for each City and find a thing or two I want to do but also spend a day walking around. My parents always had me go into churches too, so whenever I see one I tend to go in. If you know of any impressive churches I should be sure to visit on one of my tour days, I'd love to hear some. Thanks Devac!
