It’s brilliant you’ll have a great time! Moo moo steak house was really good. I did auschwitz & salt mine tour in the same day was about £50 all in (2017) picked up and dropped off at the hotel door. The salt mine is unbelievable! Walk around the castle ground which is close to the centre. Schindlers factory tour is really good aswell if that’s your thing. There a great little underground pub called “English football club” which has load of character.
