I'll be there as early as I can so help with general dogsbody stuff. Cars can do sounds, my rear speakers connect via a computer power connector, I can get an extension cable to get the speakers out the boot and pointing in the right direction, have a sub for boomy bits too! The Argos website isn't working for me at the mo,..... but looking in the catalogue (you can but the numbers into the website when it works) There is a 2.7x2.7m Marquee (2.5m high) for £12.99 (650/2210), but has no side panels The box next to that is £29.99 for a 3x3m (2.6m high) one with no sides (650/2904), but for a mere extra £29.99 you can get 2 plain and 1 windowed panel (650/2911), so £60 for 3x3x2.6m with three sides, it's a bit cheap looking I think the best deal is a hexagonal one, "4m from corner to corner" 2 fixed sides, and 4 entry screens so we can shut it when it gets cold, also has fly screens, doesn't look to bad either, it's £49.99 (650/1455) I'd get the last one for hanging out, and the first one (with no sides) to cover the BBQ, we having one arn't we? Of course that means finding £50-62. It might be cheaper to rent for the weekend, but I've not looked into that
