I have the use of the house from about 11:00 - 5:00 pm on December 10th as The Herd are planning to go to the zoo (and I am deemed too slow to join them).
I have space for 6-8 and can run 2 systems if there is sufficient demand/kit. BYO music and grog and any kit, particularly swish DACs, that might be fun to listen to.
Excuse the short notice, the possibility of the bake-off was only confirmed this afternoon.
EDIT: There is an excellent and very reasonable Thai Restaurant on Allerton Road (about 5 minutes stroll from my place) that can accommodate us for dinner if people want to eat before driving home. Let me know if this interests you also. It is vegetarian friendly.
