The fastpass for a show - such as World of Color or Fantasmic - allows you access to specific viewing areas - they are not always anything fancy and it still pays to show up as early as you can if you want to get prime viewing space from within that section - but if you are going to view the show then pulling a Fastpass for this is easier than just winging it at the last minute and trying to find a spot to view from. There are not to be confused with the viewing areas reserved for VIPs or dining packages - those are much better but come at a price!
