Its my engagement party soon, I am having a BBQ in my sisters large Garden. I have 25 adults going and 7 kids. It will be end of June so hopefully nice weather but we have borrowed a marquee if not. I Was thinking of just getting burgers and nice sausages to keep it simple. To save cost everyone is bringing there own drink. I was also going to ask other people to bring some chairs, salads, (any other suggestions welcome) Can you still hire glasses and things!! Any advise or tips to make it a class day much appreciated!!!
