We are worried about this also, and just got off the Magic a week ago, but she was still in pretty great shape, a few normal wear and tear issues but overall we were very impressed with how well she’s been maintained, diminished our fears a bit, I think the Magic and Wonder probably have another decade of life left in them, at least until the next class of smaller ships start sailing to replace them.
With all the backlash against the mega ships I think the future of cruising is mega ships to private islands and booze cruises but smaller ships to the Mediterranean, Europe, Scandinavia, Alaska, etc…
There’s a market for both.
