What I found is that most of the time the wait time is heavily exaggerated. We tend to avoid it midday as that should be it's busiest time. So we either ride in the morning or preferably at night. At night we normally ride sometime between 8pm-park close. We'll normally get in line when it's anywhere from a 75 minute wait or less because we know we won't be waiting that long. The line moves pretty fast.
I always felt like we moved through pretty quick and never felt like we waited the wait time that was posted. One this past November or December when we rode it at night, we got in line with a posted 75 minute wait. I decided to time it with my iPhone and from entering the line until getting in the seat on the ride, it took 30 minutes.
So as long as it's not the busiest time of the day and the wait is 75 minutes or less, we'll ride it (mainly only at night because it's better then)
