Practical, though, when you have five cats, a dog and three kids.
My own experience of laminate laying: I had a small kitchen in a flat a few years ago. The instructions said "leave 20mm around the outside for expansion". So I did. But there's no way a four foot wide laminate floor would ever expand that far. The stuff seems extremely "stable". IF you go for it, best advice would be to rip off your skirting and lay it under that, with a smaller gap hidden by the skirting board once it's back on. And prepare to re-hang/lift/plane off the bottoms of all your doors.
Oh, and buy decent stuff. The cheapest laminate is godawful to lay - the "lock" part of it seemed to be made out of cardboard. My first floor luckily floated away when my washing machine leaked, so, in kitchen floor #2, I bought and laid better quality stuff, which was the bees' knees.
