Has anyone recently been to Disneyland?

i'm thinking about taking the family to the disneyland in anaheim, and we went about a couple years ago and we got this thing called a fastp. It helps you on the rides with big line ups. Has anyone heard of this? I know we had got it back last time we went but i'm not sure about exactley how we got it. Does anyone know how to get it and how much it would exactley be?
