Same for a couple of nights ago. The quick one was just under 25 minutes, the other 2 rides were closer to 30 minutes each. We topped it off at 3 rides so we could still go do other things.
The problem too was that it's only a 3-hour After Hours event. The park closed at 9p and AH was 9-12, which meant day people were still getting in line for FoP up until 9p, so even though they allow the AH folks the fastpass line, you're still waiting longer...which cuts into those 3 hours. Long story short, you'll get more mileage for EE than FoP, especially at the beginning of the event.
