The Parallel Worlds Travel Agency was bafflingly seeing very little business, or rather, for some perplexing reason the higher-ups wouldn't advertise and didn't charge enough to break even on each holiday they arranged. So it was stuck as one small unit in one small mall in the middle of nowhere. They had managed to circulate some brochures locally, hopefully it'd bring in some interest.
Their unique vacation technology let holidaymakers input a set of criteria, and their miraculous Paralleliser would find the closest alternate reality to those preferences, and project their consciousness over their counterpart's in the parallel world. They offered several themed packages, even a rather raunchy getaway where the holidaymaker would become a porn star and receive a copy of their own movies when they returned to this reality.
But alas, unless someone happened upon a brochure or wandered in, the little business sat without much patronage. Maybe today that will change?
