They heavily prioritize fast lane over normal customers. We waited for 2+ hours for every ride while fast lanes walked on in no time. This not only makes you feel bad but also means that normal customers will go on far fewer rides. If it takes a fast lane person 15 minutes, and a normal person 2 hours, then each fast lane customer uses the equivalent of 8 normal riders worth of capacity.
So when you see a line of 10 in fast lane, know that it's effectively 80 people in front of you.
