Right, well in the absence of anyone else doing, i've possibly got us a venue.
It's in Southampton about a mile 1/2 away from where the M27 is a junction away from the M3. So not in Southampton centre, but easy to get to.
The cost for the room - large room that can hold approx 150 people, with a small stage in a corner - is £180.00, £100.00 of which is a refundable deposit.
There is ample private parking, and we can make noise. the only draw back is that it's on the first floor and there is no lift.
How does that sound?
Now we just need a date...
