If we do this (or regardless), it would be convenient if we added a "use another shelter map" link to the final page when we finish the choice adventure, so you can repeatedly do "use map" and "go to goal" until the maps are used up.
If you try to use a map and are not transpondent, you get a failure - "This map shows the location of an underground complex on Ronald, and you have no way of getting to Ronald right now." according to the Wiki. We should add a "use transponder" link to that, just as we do when you try to adventure on the moons after the effect has worn off.
If you try to use a map and have no adventures, you get a different error message - "You don't have time to go to the moon, man." says the Wiki. We can't do anything about that, but when you see it, you can overdrink or something to get more adventures. We could add a "try again" link, assuming you get more adventures in the GUI.
I think those mods would make your proposed links convenient enough; you get to decide when to get transpondent and when to get more adventures.
