Plus I think prohibiting excessive usage of wood on the interior should be given special leniency for vessels that are a historical replication and used as floating hotels of sorts. I could understand if the replica was meant to actually sail the seas. But I think if Olympic and/or Titanic would be rebuilt as a floating hotel, I don't think the wooden interior should be a concern. And to my knowledge, fake wood would look less like the actual wood used for the iconic interiors used on the ship, and could probably be less durable and manageable as well, I think. Besides, to my knowledge there hasn't really been an issue with her wooden interior in the past, especially in terms of fire. If proper fire safety is employed, the Olympic and Titanic's wooden interior would be no issue. Personally, I think using fake wood, or even opting out of those wooden interiors entirely would due the Olympic-class liners a disservice. And I REALLY hope the Romandisea Titanic replica doesn't get affected by this.
It should also be noted that the information also stated that the RMS Queen Mary 2 was given high exemption to the lifeboat regulation.
