Small
They were very spacious, some even had two rooms. Fancy paintings and so on. Only the very wealthy were in first class.
It is a small cabin but is was clean and it is near to the hull of the ship.
the rooms of the titanic were meant to look like rooms that would be in a hotel and were a great deal nicer than those on the lower classes as would be expected from a first class room.
they looked like the suites we have now on our cruise ships
It would be difficult to compare given that over 100 years have passed in terms of the types of luxurious amenities you would find on an ocean liner or a cruise ship today. That being said, if you look at the accomodations the first and the second class cabins had, they had the look of a high class hotel of the period.
they had a panio and anything that they brought them self.
It was enormous!
There are a few places that have Cabins with Jaccuzis in the Smoky Mountains. The best places to look are those places listed as resorts or outdoor high class camping areas.
they look nice to some people, and they work like houses
First class (or business class) sections often have larger, more comfortable seats with more leg room. They are sometimes divided from the rest of the plane by a curtain or are in a different section of the plane entirely (ex. the upper deck of a Boeing 747).
Second-class dining was the most luxurious that anybody knew. Some passengers even recollected that it was so surprisingly fine that they had believed that had mistakenly blundered into first-class somehow.
So it depends on... How much did a ticket on the titanic cost. first class ticket $300, second class $187, third class $38. Now be smart and look up these prices and put "1912 prices" after it! BE SMART FOR ONCE! LOOK IT UP AND DO THE MATH!
