Is Sims 4 Spa Day worth it?

I use the wellness skill in almost every household; it replaces fitness for some of my sims (I think they may have toned it down a little, but a Sim could get completely ripped doing yoga). Like others have said I don't typically send Sims to the spa, but a lot of the spa items can be incorporated very well into gyms and add a lot of variety (like yoga classes!) There are also several tubs that fit nicely into regular homes where you can use the different bath soaks for varying effects, like getting rid of a tense mood very quickly. It wasn't a pack I had very much interest in when it came out but the varying elements of it have integrated into my regular game play much more deeply than say, Outdoor Retreat or Dine Out. (Vampires and Parenthood are much more intentionally integrative than the three earlier packs.)

So, uh, yes. I think so. :) But in the end it depends on if that's the kind of thing you want your sims to do.
