Question: is 2 nights in krakow enough?
Answer: The old town of Krakow is a minimum 1.5-2 day thing to see the basics, and get a feel for the place. You need to add in at least one-half to three-fourths of a day for Auschwitz. That probably won't leave you much time for the salt mines. ... All that being said, Krakow can be " seen " in 2.5 days, yes.
