OK I have to confess to being a sci fi fan and sci fi fans will unsurprisingly get the most out of this exhibition. However, I believe that you can enjoy this exhibit even if you're not a hard-core trekkie.
It's nice to arrive at the Hilton on the futuristic-ish monorail. The reception hall has models of the various Enterprises hanging from the ceiling with continuous loops of various Star Trek episodes playing on large TV screens. Downstairs you'll find Quark's Bar and the gift shop which can be accessed without a ticket. The food at Quark's had fun names but looked generic and I believe there are better food options.
With a ticket, you gain access to a museum of Trek memorabilia and also a timeline of the future integrating all the Star Trek franchises. Absolutely fascinating for someone like me but I can see that it won't be as much fun for non sci fi buffs.
However, the real core of the Star Trek Experience lies with its 2 walkthrough experiences. You can choose to do either or both with your ticket choice. Now to really enjoy these, you have suspend belief and just go with it - pretend you're in an episode. I don't understand people who go into something like this with a cynical attitude from the start.
I liked the original Klingon experience - highlights being able to stand on the bridge of the Enterprise and the transporter room. It ends in a motion type simulator for a wild ride back to Earth - guess which town you end up landing in!?
However, for me, I preferred the Borg experience. You have to watch carefully to see what happens to all your fellow crewmen when the Borg attack. The highlight was the feeling of being assimilated - don't want to spoil the surprise.
Both rides ended back in the gift shop. I spent a good 2 hours in there. The reason I'm awarding it 5 stars is the attention to detail. There are actors wandering round the whole Experience area dressed in full klingon/Borg gear and they stay completely in character the whole time. For example, the klingons speak fluent klingon I only know a few words) and maintain a superior air in the tone of their conversation to you.
So 5 stars for trekkies and 4 stars for the non-assimilated.
