:smiles: Why not have it at your home, if you dont have enough seating, just get everybody to bring their own fold out chairs, we call them BBQ chairs, then also everybody can bring a plate of something, whether it be a small savoury or a dessert of some kind, or even have a couple of mains, just organize it with your guests, on who brings what, or keep it as a surprise, just hope you dont get doubles or triples on the dishes.
Also you can get them to bring their own drinks ( Alcohol ), and you just supply the "Tea, coffee, juices, cordial, soda's, cold water, and your own plate or dish, then it works out cheap for every one.:D Just what I would do!! see what u think. Another idea is to take turns having it at each others places, works out fair that way, You could still do all the same things, its just that the host supplies the drinks, apart for the Alcohol, unless you want to.
