How many rooms were there in the titanic?

Answer 1

According to "Titanic, the Ship Magnificent" by Bruce Beveridge, Daniel Klistorner, Scott Andrews, and Steve Hall, here's the breakdown of cabins:

First Class: 370 + 4 sitting rooms

Alternate First/Second Class: 46

Second Class: 122

Alternate Second/Third Class: 40

Third Class: 257

During the James Cameron special, "Titanic: The Final Word with James Cameron", they give the figures without the alternate staterooms as:

First Class: 370

Second Class: 168 (the First/Second Class alternating rooms were added to the Second Class numbers)

Third Class: 297 (the Second/Third Class alternating rooms were added to the Third Class numbers)
