Single Rider lines are an amazing way to get onto everything that much quicker! I got on twice as many rides as I would have if I didn't use single rider! Alot of the time you will even be in the same car as your family, just seated behind them instead of next to them. I wish more attractions had it available. At the end of the day, does it really matter if you sit next to your family/friends on the ride? It's not like you are going to be talking to them.
