Yeah I got to see Star Trek the experience back in June 2006. It was awesome! The Borg 4-D invasion was my favorite of the two rides, but I did the Klingon Encounter, too. I also had dinner at Quarks and talked to the Klingon actors. It was fun!
I had read a while back that they were trying to re-open Star Trek the Experience at another location in Vegas prior to the new movie, but it never happened. I think all the sets and contents of the Star Trek museum have been sold or auctioned off by now. So, considering that, and how long its been since Star Trek the Experience closed, I think the chances of me getting attacked by a shark, struck by lightning, and winning the lottery all at once, are greater than Star Trek the Experience reopening.
