To clarify...
We're looking at a pretty much full hall pass. We love couple/ couple play, but the reality is that it's difficult to work out. There has to be attraction between the parties involved, couples tend to have kids, so babysitters are involved, it has to fit social schedules, etc. We both think a hall pass scenario would be help us better realize our kinks without all of the work.
The problem, as has been stated, is that hall passes tend to be vilified. So no one advertises them. We could go the SM/ unicorn route, but those seem to give off a strong "marry me" vibe. We're happily married and not into poly, so yeah. No thanks. Couples/ individuals in hall pass relationships seem like a safer route.
Any other advice on finding hall passers?
