Are these matting things that good you can sit around and walk around in bare feet with no sand or dirt getting on your feet ?
a lot of the time, yes... also not too bad in wetter/muddier conditions (within reason).
we tend to stay in big4 parks a lot, and our boys love the pool, so when they get back to camp, they are not creating a mud pile in the area near the door or the kitchen.
also, means that young kid's toys and ipads etc are not as easily lost or damaged...
for the price, i don't see what the issue is... if you don't want to use it, don't.
we do and it works well.
