I have Pergo in my entry way. Surfie did his business on it one day when my hubby was babysitting.
It did warp, but went back down within 24hours or so. Don't know why, but I was very happy. I am going to Home Depot today as I am doing the same thing, they will lay it as well. Just remember Nik, when you buy the boxes and all the other stuff you need, open all the boxes, they need to air out for 24 hours. It makes it easier to lay. Noy only that, when my entry was done and I opened the boxes, there were a lot of ends that were damaged.
