Laser Park for fun ... and sport!
I went there with 11 friends and we had a lot of fun. I also know for fact this is a place appreciated by Erasmus!
You need to book in advance and it might be that you will be in the room with other groups if the amount of people is unsufficient which is totally fine as anyway I was shooting on everything that moved!! J I recommend coming with some drinks as it is really tiring : you basically shout, scream, run and jump for one hour and there is a lot of adrenaline in the process !
You can get there easily by tram which is the easiest way on Zablocie street and price as a whole group is quite cheap (you pay more to go to the gym and you don’t have the same fun but you sweat the same!). We tried different game modes which I forgot now but I’ll definitely go back there when I’ve a chance. You will get hot but you will have fun for sure!
