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.
