" It would be cool to have someone to find the venue/split a taxi with!"
The venue is just a three minute walk from the train and bus stations, a taxi is not really needed unless the weather is hideous. If you ask for directions to the Tesco superstore, you will be pretty close. The store exit on the south-east corner is metres from the venue.
From the train station:
Leave the station in the East direction, cross a pedestrian footbridge over a dual-carriageway. Once over that, take a flight of stairs on the North side down to the road-side. Go North for 60 metres, until you reach a road junction. At 'two o'clock' is the Tesco store and large car park around it. Head for the store entrance on the corner, then carry on 50 metres eastwards. Ibis/Forum is on your right.
