Tents: Not game-changing, just something I would like to see

[Punchtoface]

I have not managed to play literally all versions of Final Fantasy, but in the ones that I have had the chance to play, there are tents.
I have brought this up as I would like to see them, especially the tents from Final Fantasy 9.

I am aware that a tent would be obsolete, assuming there's no difference in it's purpose.
Therefore, I would like to propose it to be implemented as an item to provide some sort of a Well-Rested buff which can be used (out of battle) up to a certain number of times. A good number would be 8, for a full party.
