What happens is you get a fast pass,then go into a new area.After that you need to go back to the world (without using the fast pass),if it still says You can get a fast pass Do not just go into a game area and try to enter a game,doing this the game will think you still have a fast pass and not let you in.
Short/easy story:
I entered in a world that needed a fast pass so I grabbed one,then I entered back in the same place and my fast pass vanished.I can now not enter games because the game thinks I have a fast pass
