If possible have them get the mask/snorkle/fins and figure out wetsuit rental size ahead of time. Then practice swimming in a public pool or wherever with the mask and fins (yeah snorkels suck but maybe that too). This way only the scuba gear will be new, not the mask/fins thing which can be surprisingly troublesome for newbies, especially the mask. Oh, and booties. Everyone needs their own booties. You know why.
