My wife and I and our two sons will be going to WDW over the Canadian March break for the first time. I have heard so much about the fastpass, but know so little about it. I understand it is a way of avoiding long line-ups on the rides. Could someone please give me an idea as to how they work and how to best utilize it while we are there. For example, can we have one fastpass for each of us or can you only have one in total? Where do you get the fastpass? Thank you for any and all input!
