Find Your Cruise
Every one regardless of race colour religion gender political opinion single married unattached are welcome on cruise ships yes you will get some prejudices but you will get that anywhere.

No. They are not "geared" or engineered in any way. Just go and slot in like all other cruisers and you'll love it. ... Neil.
