Of course, we'd seen the movie and had our kids watch it before we visited Branson. I'm glad we did. When you arrive, you are greeted by staff in period costumes that inform you of which passenger you are, which makes the whole experience a bit more fun as you learn their fate.
Before going in, the staff explained the listening devices and I kept waiting for "...and they are only $20 dollars), but that didn't happen! I recommend grabbing one since it was nice to hear more information on almost anything in the exhibit.
As you enter, there is a model of the Titanic, which is really incredible.
Farther in, some highlights as you progress take you from the 3rd class (those rooms! oh boy, I would not have fit.) up through second class, and finally first class and beyond. There are tidbits to learn all over, and it is well worth stopping to learn what you can. They had a Jewish kitchen?!? Who knew?
The exhibit ends on a really cool high note with the captain's view (and beyond). I don't want to give it away, but when you see it, there is something out there that I just don't understand...at least its purpose and what they are trying to convey to us.
In any case, this was really great I'd suggest trying to go as early as possible. We were there right when it opened and I think that probably works best.
