There is a Stagecoach bus that departs just around the corner from the railway station, It is the No. 63 towards Rugby and departs hourly at 42 minutes past the hour. It will take you to the roundabout where the A425 crosses the B4455. From there it is a five minute walk to the exhibition centre through the car park.
If you have a bus pass it is free, or rather someone else pays! If you walk through the snicket under the railway line towards the town's main street the bus stop is outside All Saints' Church. Alternatively, walk under the girder bridge and turn left into Bath Street at the traffic lights and just keep walking until you see the church on the right. From memory, there is no signed bus stop for the return journey to Leamington but the bus stops exactly opposite the signed bus stop on the other side of the road where you alighted. I used this service last year to avoid paying for the shuttle-bus and will do so again this year as I have a B&B booked in Leamington for a couple nights.
It's so much cheaper than a taxi even if you don't have a bus pass.
