but if there are any other suggestions then please let us know
There is a place by the Forum Hotel (sorry don't know the name of the company who run it but others on here might). They also do paintballing here as well which I know is a stag do favourite. Went with some of the guys on here recently so someone on here should be able to tell you the company name. It was a great day and well worth it.
Welcome to Krakow. Have fun.
