I have put in a lot of laminate flooring. The glueless is really easy to put in. Once you figure out which direction you are runing (usually parallel to large walls with windows), you mainly need to make sure the first run/course is straight as possible and parallel to the wall(s). After that, just keep working down, carrying the leftovers to the end of the next row so the seams don't meet. Beyond that, they have made it as easy as possible. The old glue kind was a major pain in the butt, but I did my wife's 800 square foot craft room is about two hours.
One tip is to never force two pieces together that don't want to snap as it will chip the piece. A second tip would to never tap on a piece directly - use a scrap piece or the plastic blocks that are available.
