There is actually
no useful information about the Tour's whereabouts. Based on attendance reports (anecdotal though they may be), I'm guessing the thing has closed up shop, at least until more backers or suitable location can be found.
Frankly, the overall experience of...er...The Experience blows it away. Of course, I'm admittedly biased.
It was fun to walk the D's corridors and look in on sickbay and the crew quarters and the sheer amount of
stuff was pretty cool but it was not presented well, IMHO.
If it ever does make it out of mothballs again, it's worth the price for Trekkers, especially if you can get half-priced tickets like I did.
