I'm going to go against the grain and say laminate, especially if cost is an issue. We have a home daycare, with 8-10 kids in the house every day. I put Pergo in our kitchen 5 years ago and it still looks great. It takes a lot of abuse and cleans up at the end of the day with just a damp Swiffer. Granted, it won't fool anyone into thinking it's real wood, but for the money I can't complain.

I started out with nothing & I've still got most of it left
