Save this one for your next Dote day

Work your way through the galleries in the angular, ship-shaped building on the slipways where the Titanic was built, from the shipyard and the launch to the sinking and the wreck.

Why it's a good date: It's a story you both know, told where it actually happened, and it's easy to spend a whole afternoon in. Walk out onto the slipways afterwards to see the outline of the ship marked on the ground.
