Food for thought. This applies to everyone not just DAS. DAS is not always the fastest way to go if the stand-by time is something manageable. As pointed out, the fastpass line can be longer than your expected time. The CM checking fastpasses doesn’t truly know the situation inside. I’m going to use nice round numbers but: you enter a line at 9:00 am with a “15 minute wait”. There were 40 people let in at 8:30. Of those 40 people person 9 decided to roll/stroll through because they want to enjoy the theming of a ride and not just use FP as a quicker method to get on. You are now behind the remaining number of the 830 group , 30, PLUS however many people are in front of you from the 9:00 slot. This creates a domino effect. Of course, you do have the people who only want to go as quickly as possible through the line but the theming of a ride, IMHO, is just as important. The number of “gotta go now” people is usually greater than the number who want to go leisurely to enjoy the experience but you can’t always count on it. Just food for thought.
