I've not been to world, but anytime there is concrete stalls I either rent stall mats or put down the puzzle pieces two layers thick! I think that's four packages of them from Sam's.... And plenty of shavings!
I use the connected mats from lowes. $20 for four. I then put duck tape on Every 2 and it seems to help them stay together better. My horse likes to get antsy in the stall. I don't use but 2 bags of shavings. Just make sure you get some disposable gloves when you get ready to pack them up
