We have been sailing Crystal since 2001, on the Harmony, Symphony, and Serenity. Usually we do back-to-back cruises (our last was 35 days from Valparaiso to Auckland on the Symphony in a PH cabin). It will be our last on any Crystal ship.
Now that Crystal has chopped up its cruises into mini 5-day segments, and "relaxed" its dress code, it has become a down-scale cruise line. We have always avoided those 7-day cruise lines because we didn't want the 7-day cruise clientele. Now, that is who pretty much populates Crystal.
There was frequent loud, vulgar cursing around and in the pool by clients who have obviously had too much to drink even at 11:00 AM. Baseball hats, flip-flops, athletic shoes, and t-shirts are common in the main dining room. Just read the reviews here on CruiseCritic from Crystal clients lauding the fact they will not even bring a sport coat onto their next Crystal cruise.
There was a man in the cabin below us who smoked cigarettes on his balcony, despite it being explicitly prohibited by Crystal. We couldn't use our balcony or open our outside door without having to inhale his second-hand smoke. We complained to the Concierge multiple times, but Crystal was impotent in having him stop. So, WE (not him) had to change our room. Terrible.
On the good side, Crystal does have great service. The staff is outstanding. With the elimination of set dining times, the food appears to have gotten even better.
We have cancelled all future cruises we had already booked with Crystal.
