SIRandyraven - //I'm not jealous and have had the opportunity to join family on these types of ships in the past.
However the thought of joining 6,800 other passengers in a confined space for a couple of weeks fills me with horror. I have so many reasons for not wanting to join one of these cruises.
Then when you make it into port, you and several thousand of others then have to journey from a port to the main tourist attractions , where you have X hours to enjoy yourself and then back to port so you don't miss the boat :-)
No thanks //
It is apparent that you have not been on a modern cruise liner - the experience would alleviate most of your negative thoughts.
Even the average-sized modern liner has a vast mount of space, there is never any sense of overcrowding or limited space.
When you arrive in port, there are usually several other cruise ships in dock as well, but again there is no sense of overwhelming numbers of people. Arrival times are staggered, so the docks are never crowded.
The cruise company lay on trips to the tourist spots, but we always make our own arrangements - there are dozens of cabs and minibuses at every port who will take you around, usually for about a third of the official trips.
Since in the vast majority of ports you can disembark at eight in the morning, and not have to return until five or six in the evening, that is ample time to sight-see and get a flavour of your destination, and decide if you may like to return for longer, or not.
You may be surprised at the variety of experiences available on board - lectures, films, shows, demonstrations, a library, a theatre, a cinema, a casino, and so on.
You should give cruising a try.
