Idk what to call AW, but here's wat I think of the grass. It helps like bloody crazy any day 30^c+. Everyone at AW walks around barefoot (you can't wear shoes on a slide etc). If I wanna go from the abyss to Kahuna, I can do so barefoot without getting 3rd degree foot burns. And where there isn't grass, like the walk up to inferno/Kraken, there is shade. Most families don't go on water attractions, put on shoes dry, take off shoes (process repeats). It's branded as an all round park, so these 'unthemed wastes of picnic space' is intelligent, and so they don't get sued (unless your an upcoming talent being an idiot on kraken🙃)
