 Probably won't be an issue, but it's worth keeping in mind that all flat "grassy" areas (yards, areas around sidewalks, etc) come with a very real risk of stepping on a small cactus with razor sharp thorns that will go all the way through just about any shoe or sandle. Loose sand is generally safe, grassy yards can be dangerous af. Some houses have brought in sod & work to keep the cactus out, but that's not really the norm. 
 Thast not what I was expecting you to say 😂
Thanks for the heads up! 
 I had some friends who didn't know learn the hard way on the first day & kinda ruin their week. Once you know what to look for it's generally not an issue.
