From a person who does not get the whole "Trekkie" thing yet who lives with one this in my opinion ( before going ) was a waste of money and time.
However money wise the tickets are a bit pricey. $39.99 for non locals but if you hit one of the vendors up on the strip that are called the "half price tickets" we got a nice package deal.$44.00 for the two rides and the backstage tour which would have normally been over $68 a person
With friends who were in town from Austin who wanted to go see this we all went on the backstage tour as well. Now that was the best part of it all.
All In all I can say that it was very interesting, I lost my fear of incredible trekkie dorkness upon entering the doors. For those of you who love the whole Star Trek Phenom you must must must go there when visiting Vegas
