Our hours were 6-8pm. First hour I counted 4 kids, fortunately second hour stepped up a bit to about 40-50 total. Not disappointed considering the nasty weather and the fact I was really the only house decorated at all. Probably 3-4 other houses with porch lights on at all. Man I wish I lived on a "Halloween Street." Oh well, at least I am the "Halloween House" on my street.
Mine came with a vga cable....you could use that to connect to your laptop if it has a vga out. When you say TV...do you mean it has a dvd player built in? If so, does it have the red/white/yellow outs? If so....you can connect with those. Most any dvd player should have this type of out that you can connect it with.
