Because new tags may be added at any time and enquiring into them is tedious without SEDE (which is only run weekly and seems not fully in sync even so) it is difficult to be sure, but self-guided may at present be the only tag on the main Travel site without a Usage guide of sorts.
As an adjective it does not, in my opinion, make a good tag. self-guided-tour may be more suitable. However that is not quite how the tag is in use at present for four Open questions (and two Closed):
Q: Are there self-guided tours in Boston/Harvard?
Q: Self Guided Northern Lights Tour
Q: How to find people to do long hikes?
Q: How can I travel to the “Eye of the Sahara”? Are there tours? Can I self-guide?
tour-guides is a synonym of guides so an alternative might be to retag the four with tours, but the Usage guide for that is:
Organized tours as opposed to travelling or seeing things on your own. See also the "guides" tag.
thus would then have to be rewritten.
There is, IMO, justification for something like self-guided but a sensible Usage guide might be easier for self-guided-tour.
- Should self-guided be burninated?
- If not, should self-guided be renamed, and if so what to?
- What would be an appropriate Usage guide for whichever tag is chosen, if one is?
