We were on the July 14 sailing of the Century sponsored by my in-laws 50th anniversary. My wife and I are 5 time cruisers, mid 40's with two teenage daughters, 14 and 13, and we all sailed as a party of 11.
Yes, the ship does not have the amenities of the more recent liners, but the Century is a classy ship with great staff who pulled out all the stops for us to provide a great experience. We also benefited from tremendous weather, lots of whale sightings and very little ship movement on sea days.
Like any cruise, and we've been with 4 different liners, there were occasional hiccups however everything was resolved to our satisfaction immediately upon bringing it to the attention of the crew. I won't bore you with any details or complain about trivial stuff on-line, all I wish to say is that the response was top notch every time.
Smaller than average it seemed but rarely did we spend any time there.
