I assume you are talking about hosting instead of getherwing joining. The main thing about hosting is that after that first game you win, if you keep the players on (saying "Yes" to playing with them again), you get put back in a lobby that has people joining immediately, even if all the original players leave. I'm not 100% on how this works, but this is a theory: basically, the hosting system runs on a first come, first serve basis, so when you make a lobby, you're at the back of the line. However, the system also gives priority to hosts who successfully completed a game and is keeping the same lobby going, possibly to ensure if only one person leaves, 3 people aren't waiting long compared to the single hosts in the line.
So I basically continually hosted, said yes every time at the end, and kept a winstreak going, which could drain all my stamina fairly quickly. Something you can do to make the initial wait better is create a room, then set it to private while you go do something else for a few minutes or so. Even though no one can join, you still keep your spot in the system, so when you open the room later, you're now closer to the front of the line for people to join you.
If you're talking about getherwings, I always found the wait time relatively short, so I had no big issues finding games.
