Tips for using GACs (specifically with the alternative waiting area accommodation):
1. Evaluate the situation. Don't immediately use the GAC if you don't know how bad the situation is, wait for a minute and look at the line. Check the length, speed, and if there appears to be a second waiting area.
2. Ask the first host/hostess you see about an alternative waiting area
3. Follow their directions and when/if you can't find it, ask another cast member.
4. Find the waiting area and wait until a cast member comes. If it is an area where random people could just be sitting on benches or something, make yourself known. They might think that you are just randomly sitting/standing there.
5. Ride the ride, and pay no attention to what others say when you 'cut' the line to get on the ride, you did wait.
