We think a bash in the Bath area would be a great idea. The Out and Out sounds a good option, we had thought of the George at Bathampton but there's no kids play area and the food's pricey, although it has a big car park. There's also quite a big pub at the bottom of the old A46 out of Bath, next to Alice Park - we'll check it out as an option. I think once you post the event on the main site it will generate a lot of interest.
