I recently did this. It is really good looking and I love not having the carpet dirt trap. My experience is it was very easy to install the plank, but as time has passed I'm noticing some separation, probably due to temperature induced expansion/contraction. I believe this could have been cured by using some flooring glue...esp. in the slide area. The other problem area I noticed was the overhang from the slide. At the joints, the planks were easily damaged. I glued a 10" long, 2" wide piece of plank on the underside of the joints to mitigate that problem and it words well.
