So far, the reports have been that yes, FNSV has been open for EE. That is not a guarantee though. Even if it is, it would be a better use of your time to ride FNSV first thing on a non-EE day and spend your EE in Fantasyland/Tomorrowland where you can get more done. Lines have been reported here and other forums as being up to 2 hours long at the end of EE. If you have multiple EE days, maybe use 1 to stand in the line, but with only 1 I would keep clear of that area. And no, FNSV does not have FP.
