For a big ship, the Koningsdam offers some hidden gems where you can mingle or get away from crowds. We especially liked the Dutch cafe for a quick lunch and coffee.
Embark/debark: everything went smoothly. We caught a Rome Cab from the airport directly to the port. On arriving, we waited in a "lounge," but there were no issues.
Cabin 5110: Vista suite -- not as nice as Signature Suites on other HAL ships and not worth the extra costs above a verandah suite, save your money IMO.
Well maintained and adequate storage space. But for the price, it's not as spacious as the Signature Suites on smaller HAL ships and it's not really worth the extra money paid beyond what you receive a standard verandah suite.
