I have invited loads of relatives (17 adults + 15 children) over for a couple of days in between Christmas and New Year. The children range from 4 - 16. We've got a large, dingy basement which we are going to try to transform into an exciting place for all the kids to be so that we, hopefully, get to talk to each other for a while. Yeah, right. Anyway, that's the idea. So far we've decided we're going to borrow a projector so we can show films (Shrek, Star Wars maybe) against one of the big walls and we're going to cover the cobwebby old boarded ceiling with sheets a la Turkish knocking shop. There are only 2 power points down there though (we will be running multiple extensions from them but DP assures me he knows what he's doing) so has anyone any ideas about heating? Lighting? i.e. with both, either cheap or easy to borrow and not dangerous. We're going to put most of ds's toys down there, 15 sleeping bags, loads of popcorn etc. Any other good ideas for making it more interesting than bothering us lot upstairs? Any ideas gratefully received.
