We've been cruising for over 30yrs at a rate of 1-2 per year (mostly on the "mainstream" lines with which we're all familiar) and have seen the size inflation as it has progressed. Currently, we have four cruises planned for the next 2 years. We have no "brand loyalty" and book ahead based on price, ship, and itinerary.
To this day, our finest overall cruise experiences were on the old Pacific Princess (the Love Boat) which was TINY compared to current standards. Buy, boy did they treat you right! As said by others, the ship spent many years of Summer months sailing back and forth between NYC and Bermuda at a reasonable cost.
We must have taken that cruise each summer for six or seven years in a row and, yes, the crew had little turnover so friends were made. The Hostess (not cruise director) was named Joy and we became yearly friends. Yes, she was British. The Mater Dei was named Lorenzo and he expertly ran the place with a firm but consistent hand. I believe he spent his entire career singularly on that ship. Joy was also a "fixture" on the ship for many years but I think Lorenzo was an original crew member.
We were on the ship on 911 and sailed past the WTC the day before the attack. It was a beautiful day and we still have a photo with the Twin Towers behind us just 36 hours before they were gone. We were all smiles with some Canadian friends and holding adult beverages. Who knew?
We again sailed on her during her final season just before she was retired and sold. I think that was the year following 911.
We love to cruise and our fondest (cruise) memories are from the original Love Boat which was (I believe) only about 26000 tons.
