It's an excellent attraction / very well done. We've been to it twice. Next trip we're thinking about doing the new dinner theatre experience that they have there. They have a retirement party for Captain Smith and relive the sinking. Each table has at least actor sitting with you during dinner. Reviews I've seen have been very good. Last March they were just doing this on Saturdays.
The Gatlinburg one is a different museum (a sister museum to the museum in Branson). The Orlando one is owned by a different company. There is also the Titanic artifact exhibit that has traveled to various museums mostly in the US and Europe and a version of that with the piece of the hull in Las Vegas (five year contract there). These are all quite similar, so unless you are a huge Titanic enthusiast, I would just recommend doing one of these. I would highly recommend doing one, though.
What I really loved about the Orlando one that the other ones don't have is a personal tour guide, an actor in costume and accent that takes you through on a guided tour (a very nice touch). Others are self guided with the option to rent a head set. Most people even those who are not particularly interested in Titanic history I believe would find going to one of these very enjoyable, and the Orlando one is an outstanding pick.
FYI: Our recent Titanic touring and plans for later this year and 2012 -- Anything worth doing is worth doing to excess -- LOL
My son is a big Titanic enthusiast, so I've been to the one in Branson twice, the one in Orlando twice, the traveling artifact exhibit once (Indianapolis), and the more permanent artifact exhibit at the Luxor in Las Vegas (twice) -- at the beginning and at the end of a Utah National Park trip. We've also been to the Titanic memorial in D.C. and the Titanic pier in NYC that has the old White Star sign. In December on our way to Colorado for a ski trip, we'll see the Molly Brown house in Denver. We'll be in Dearborn, MI at the Henry Ford next June to visit a cousin of mine and to see the Henry Ford and Greenfield Village (and what do you know -- the traveling Titanic artifact exhibit will be at the Henry Ford during our stay, so we'll see that again to my son's delight). And in August we're taking a cruise out of NYC to Canada, and one of our ports is Halifax, NS where we'll see the Titanic cemetary (those recovered from the ocean initially are buried there) and the Maritime museum in Halifax that has a whole floor dedicated to the Titanic. // We're also registering regularly in a free trip drawing sponsored by the Branson/Pigeon Forge museums to win a trip to Ireland and participate in some of the 100th anniversary of the sinking activities/events. It's highly unlikely we'd win that trip, but I've figured out how I'd pay the taxes just in case.
