As inferred from the title, this is Rin's journey to a sauna, and without Nadeshiko popping up out of nowhere. Plus, it's not Yuru Camp without some camping. Despite sharing the title with the Heya Camp comedic shorts, this is much closer to a half length episode of Yuru Camp. OVAs/Specials often worry me because they try to jam too much content into a single episode - fortunately, Yuru Camp's already lax pace actually works really well with a short episode for a change.
You get pretty much everything you'd expect from a typical Yuru Camp episode. The same peaceful music, with a few new tracks thrown in at the end. Same Yuru Camp humor. Same beautiful art style, and moving vehicles look slightly less mildly awkward! Only complaint was Rin's helmet mask alternating between clear and looking like a solid block of aluminum between scenes made her look more like masked Misaka Worst than I was expecting. There's only so much character development you can do in 10.5 minutes and usually specials can't get this right, and following Rin around for a day far exceeded what I was expecting.
All in all, it's a typical Yuru Camp episode while we wait for season 2. If you liked season 1, then you'll like this. If you missed this, then you didn't miss anything important other than missed enjoyment. To be fair, I didn't know about this in advance and found it by coincidence. But if you're reading this now, then you know about this episode - go watch it already!
