Why are you having to daisy chain? Is there a limited number of cables between some locations?
But, adding WIFI access point(s) to the switch infrastructure is the safest way. Again, unmanaged switches will generally "just work". A separate WIFI access point connected to the switch ensures that WIFI config problems don't mess up the wired network.
Daisy-chained switches can run into bandwidth limitations (as discussed in the article I linked). A tree structure is a better implementation where each leaf switch has a link back to a core switch and router. It allows all hosts the most uniform access to all other nodes. It may require more cabling.
