In May, I have a 7 hour layover with my wife and two kids -- teens -- between arriving from DEN and leaving for CDG. I'm sure we could have an iPod/cellphone/netbook/DVD day, but wondering if there's something close to the airport that we could get to and back from. It's the youngest's first trip out of the USA, and she knows we don't count stops in an airport as a destination, so something on Canadian soil would be HUGE! Even a reasonably interesting meal would make it. We'd have to take public transportation or a taxi. I'd be grateful for any ideas. Thanks!
