I went to vegas 2 years ago with my mom and cousin. They went to a show i didnt want to see, so i went to the titanic exhibit and bodies. I thought they were both interesting. I was interested in titanic beforehand, i have that ghost of the abyss movie where they go down and get artifacts. Its a self guided tour so it depends on if you read everything or rush thru it can take 1 hr or 15min. They had an actual piece of the ship which i thought was cool. They also give you a name in the begining and you see if you survived at the end. My person died.
Ive been to a smaller exhibit at Foxwoods in CT. And i hear there is a big one in Orlando that i want to go to.
Also when i went to the exhibit in vegas, i saw Flava Flav in the lobby of the hotel it was in. lol
