I’ve heard good things and bad things about Windjammer cruises. It is true they are much more intimate, with a far smaller passenger complement. The crew is free to give more individualized attention to each passenger and to accommodate more individual tastes. You’re even free to help sail the ship at times.
The price you pay (besides the price you pay) is in smaller quarters, often less luxury, and fewer shipboard activities. But if you’re willing to forego some of the frills, these can be very pleasant getaways without the “cattle-call” atmosphere of a massive cruise ship.
Mind you, my information on Windjammer Cruises is dated and anecdotal.
Since I’m not a huge fan of frills and luxuries, I don’t think it would matter to me. In fact, when camping I generally consider a tent an unnecessary and vaguely decadent frill.
Must admit my wife has a somewhat different attitude. LOL
