Are you coming in through the front gates or via International Gateway? If it's front gates, definitely do Test Track first. If it's IG, do NOT do Test Track first. By the time you get there, the line will already be long from folks coming in through the front gates. Instead do Soarin' first then try to get to TT at around 8:50am. That's after the first wave of EE folks but before gen pub rope drop. Even if the wait time says it's long, it won't be. Works like a charm every time in my experience.
