Accountability

Beware of disreputable Mind-Travel Agents that have dismal accountability, liable to leave you stranded in some corner of the universe with no return ticket. Such has happened, such as below, travelers that received a confirmation for pick-up that just indicated "tomorrow, midnight" — but didn't leave a clue as to a date or coordinates. These unfortunate fellows traversed the Kingston III planetoid multiple times hoping to intersect their transport home.

No they never returned, and their fate is still unlearned.
