Even though I have used fastrack in the past before, I really don't think it is necessary. The majority of the queues are fast-moving, and most of the rides have high capacities. For me, just watching the rides on their cycle in the queue-line really seems to speed up the waiting time. Also, I actually prefer to have a 20 minute queue than a walk on. I know it sounds odd, but for me a ride is much more enjoyable after you have queued to go on it. Even 1-2 hour queues go really quickly for me. That's why the peak season at Thorpe really doesn't put me off going at all.
