Considering it's a slight bugger to get to because Village Buses, Ahahahaha, it would seem sensible to see if people want to organise lifts.
Otherwise you can get there by bus in about 1hr 30. In which case it may be clever to organise a bus party to prevent boredom.
As far as Jim can see, the best option seems to be the busway to Huntingdon, and either the no. 7 to 25 min walk from the venue, or a joint taxi. 25 min of the Google Maps route is walking from Godmanchester to the place.
