I have taken tons of video on cruises over the years and we do go back and look at them to get in the mood for a cruise. I have used everything from a very large professional type camera (the one used be CNN during the Gulf War) to the very small ones.
I think for the average cruiser, smaller is better (yes, size does matter!). If I were going to buy another video camera today, I think I would opt for one of the new ones which records directly to DVD's and forget tape all together! Tapes do age, they can break or the cassesetes can and do fail and most folks now have a DVD player. If your computer has a DVD burner, you can still edit your movies.
These cameras are not the smallest on the market, but they are quite small and you will have no problem holding a tiny one steady for night shots as mentioned and the controls are not too small for large hands.
Just my thought while strolling. I too have a viewcam, problem with it is that in bright sunlight you can't see anything on the screen and it has no optical viewfinder!! I also have a Nikon and a Sony Procam.
The larger ones are less likely to go ashore with you because they become a bother! Don't know if this helps, but these are some things you might want to consider.
One last thought, go ahead and buy your new camera at home, no REAL deals in the islands and in fact the major stores will admit that they sell pretty much at US retail; however, they usually throw in little extras to make the package more attractive and you do save sales tax, but the saving are not worth no having the camera at the beginning of your cruise. (I have bought a couple of still cameras in the islands, not because they were just such great prices, but because I wanted them NOW!
