I am sorry to see it go, not only because I am a lifelong Trek fan (however dated some of the multimedia stuff was, the collection of memorabilia was first rate) but because of the countless Fanfaire memories forever associated with the place. I’ve attended many SOE gatherings at the Hilton, and Quark’s Bar was always the epicenter where fans and devs could hang out together. Many a Warp Core Breach has been consumed while discussing the latest patch or sharing war stories of a raid gone wrong.
There are hints that the Experience may be reopened elsewhere. Certainly if the franchise relaunch film is a hit, you can expect to see all kinds of updated Trek in the media. But for us diehards, the original STE will be remembered fondly as a Mecca to which we could make our nerd pilgrimage, a place where we could share our fandom and not feel so alone in the galaxy. It was a place of hope and dreams, and we need more of those in this life, not fewer of them.
