I'm going to Krakow on the 20th which is a Sunday and come back on the Wednesday, not sure whether there will be anything decent on a night during the week though.
You'd be supprised, it's a wkd place, bust best enjoyed during the Summer for me, it's absolutly baltic the minute you land this time of year. Summer however is SCORCHIN
Lol The flight on the way out must have had 5 people on it. On the way back (NYD) it was absolutly rammed, couldn't imagine Newastle being that much of a Tourist resort to the Polish.
