Describe the interior of the Titanic please?

I'm writing a fan fiction and it's a crossover that involves the Titanic and I'm having some trouble describing what the interior of the ship. When I say interior, I mean as in the lobby of the ship, the rooms, etc. It's more of a modern take on Titanic but I still want the exquisite detail and all the (dare I say it) epic-ness of the Titanic. If someone could write me a scene/paragraph describing the lobby (like when the character first walks into the ship) and one describing the rooms. They would be second class rooms if that makes any sense. If someone could that would be amazing, I'm having total writer's block :/
