We were there from 2/4 to 2/14. It was running during the early part of our stay. We rode it twice on 2/6 and five times on the morning of the Feb 8th. A couple of days later, we heard a family on a bus complaining that they had gone to AK on 2/10 and EE was not running. We went back to AK on 2/13 in hopes of riding it again before we went home, but it was not running.
A CM told us that during soft openings, you just have to hope for the best.
The funny thing is they've already changed the Top 7 list (on resort TV) to include EE as the #1 attraction. I understand wanting to promote it, but why list this as your #1 attraction when some people may not get to ride at all during their stay?
