I too crossed the Atlantic on the Queen Mary (not at the same time as PatH, in 1962). I don't want to burst anyone's bubble but I don't have glamorous memories. I don't know if the passengers in first class were seasick, but JONATHAN is right; we were down "near the boilers". I'm fortunate in having a strong stomach, but there were times when I was almost the only person in the dining room for meals, and some poor green-faced waiter had to be rousted out to serve me. The food almost wasn't worth it: it was terrible.
It was December, and the weather was bad the whole time, so we couldn't go on deck. When my husband wasn't being sick, we spent the time playing Scrabble with another couple.
I didn't get the grand Tour then, but I did 45 years later. The Queen Mary is now docked in Long Beach, California. When we moved out here, I took a historical tour of the ship. When he learned I had sailed in her, the guide took me to meet the current Captain.
Of course, the tour centered on first class (which is gorgeous) and the famous and glamorous people who sailed on her. We saw Churchill's suite, fitted up for his specifications (including an extra wide, extra strong chair, if I remember) and heard about movie stars escapades. Another world. It is now a hotel, and you can stay overnight in one of the staterooms. There is also a ghost tour, featuring all the ghosts who are said to haunt the ship.
