Hi Peter,
this is a very bad usability issue if people need to find that info in a tiny collapsed FAQ, or maybe on a description which no one read, if he got informations from other sites.
So you should 100% add the Metabox Tab like on premium, and add a note to the documentation. You can add marketing, what is all possible with premium version, like the hotel pages or other stuff.
Plugins with no fast info are horrible for plugin installer. Everyone expecting a menu because 99% of every plugin has even a small info.
best regards
