Calming yet Still Lively
Krakow is amazing. From the park that surrounds the center, the the Wawel Cathedral, the tours nearby and more, it was an amazing experience. There is a lot to see and do here that one will not be bored. I highly recommend the Auschwitz tour and going to the Schindler's Factory Museum.
Insider Tip:Get to Wawel Castle BEFORE it opens or you won't see it. I tried to go two days and they only have a limited number of tickets per day so they will be sold out by 10:30 a.m.
