There are few tips that might help get you into the staff games.
If you are timed right to get in at the start of a game, log off, then on again just a couple minutes before the game is scheduled to start. Start a search on the room list for the name of the game and maybe you can find the game just as it is starting. You may be one of the lucky few to start off the game.
If a staff game has already started, log off, then on again and find the staff game on the room list. You will probably get the "line is too full" message, just click ok and immediately try to enter the room again. Often times, if the game is a spin the generator game, the guest turnover in the room is pretty decent speed, and you can enter quickly (maybe up to 10 tries though). Be fast! If the staff game is the break the ice or race to the chair type, guest turnover will be slower. I'd say to give it no more than three minutes (with a 30 minute disconnect) before you log off, then on, then start over again.
With the vmk timer set to disconnect at 30 minutes today, everybody is having major problems getting in the staff games. If the timer is set at like 45 minutes, usually everybody is successful at entering the games, given they were not logged on too long before entering the game.
