I went to this gp last time was amazing we got wizz air flight to poznan out from luton and ryan air back to bristol as i live in live in plymouth..stayed in poznan right on the square this was my 3rd time in poznan plenty of bars and outside eating ..lake malta is close by with a great shopping centre...we then took a train on the day of the meeting to torun for a 1 night stay after the gp and returned to poznan for a couple of nights.. train takes about 2 hours easy to book at poznan glowny about 6 pounds...
tickets were bookable about 8 weeks prior to the meeting so get on the net early keep checking daily.. i think as long as you book tickets on the day you will be fine.. i thought this gp was better than bydgoczc.(spelling)..i can recommend the brovaria hotel which is fantastic with its own brewery about 65-80 per night or if not the ibis poznan centrum which can be booked on the web for less than £30 per night for the room with 24 hour bar access and about 2mins tram or 10 mins walk to the square. enjoy
