Also, the boarding groups right now literally are all gone in about 3 seconds. And basically everyone with a HS park reservation is trying to get a BG. Not all of them will get BGs. This means that every little thing you can do in order to get your phone a smidge faster than everybody else can make a difference. ESPECIALLY if you are using an older model phone. As for us, we had 2 HS park days. I wanted to maximize the possibility of getting a BG, so we did a bunch of the things recommended in this thread. It worked. May the force be with you!
