SSB has enjoyed it (been twice)... but it is very different I feel than the travelling one, which I saw in Seattle, WA.
The Orlando one is heavy on the "feel" ... but VERY few actual artifacts from the Titanic itself. They use pieces from her sister ships of the time, and such. I think the only two authentic items when last there was a deck chair, and a life jacket... that was it... compared to a slew of actual articles in the travelling one including part of the ship with a porthole (found that the most awe inspiring of all).
Both are good, but should be aware of the differences.
