You defiantly have to hit these on Saturday...
Diamondback(full queue is about 45 minutes, very fast line)
The Beast(at best will be an hour wait)
Vortex(about an hour tops)
Racer(usually no wait)
Drop Tower(about a 30 minute wait)
Try to squeeze all those in.. and if you have more time, try and re-ride your favorites.
On Sunday, the lines will more and likely be shorter. So try and get everything else you haven't ridden yet. And if you have time, go back and ride your favorites. Try and get a Diamondback and Beast night ride if you can. And most of all, Have fun and be safe!
