For those of you who may be driving and finding that the entertainment systems are to expensive, then try using a laptop for the dvds! It worked great for our family this past roadtrip. I also found that the screen for the gamecube is compatible for all gameing systems (xbox and sony) and the price is cheap. Try buying gameboys for each of the kids. Then you don't have to worry about each kid arguing over what game to play. Just thought I'd share these with you. They helped me. Also Walmart has coolers on sale (the portable plug-up ones).
