The Perpetual Line

Problem: You want to open a new hotel in Las Vegas, and are looking for a unique hook to attract visitors.

Solution: The "Perpetual Line". This is just a line where people go to wait. One person goes through the line every 10 seconds, and gets a paper with their number and maybe a handstamp or some sort of collectible ("I did The Vegas Line"). The unique thing about the line is that it never ends as new people are always entiring the back of the line. It is a place to meet people, hang out, be a part of the event, etc.
