If you're local enough that you think you'll be doing a lot of last minute trips in the evenings (like within 30 minutes or so), I would definitely go with a Premier pass. We're about 2 hours away, so deciding at noon that we want to go that evening doesn't work so well for us. We have the power pass with black out dates now, but if we lived in Deland or Kissimmee, Winter Park, etc we'd get the Premier pass.
