I sailed for 4 years but it wasn't cruises. Ex was in the Merchant Navy and wives can go too. I loved being on board ships. It was tankers so very small crew; 20-30 people on board, crew and officers. There were different canteens and bars for crew and officers. It wasn't luxurious and wives were expected to clean their own cabin, but food was prepared and served. How good that was varied, depending on the cook and then nationality of the crew. Also they tended not to be near the places you want to see, so we had to travel when ashore.
Tankers don't have stabilisers so it could be rough. Bands on your wrists or seasick pills can help, but you can't drink alcohol if you take them. Ex missed Christmas dinner one year because he had pills and then a drink.
. I got more seasick when we hired a small boat one summer, a catamaran, and sailed it to France and round the Channel Islands
Friends have gone on cruises and they do sound very nice. One of the cruise company sites has details of the various kinds of ship, sizes, kinds of place they go to. Some have lecturers on board so you can learn painting or about the countries you are visiting.
Actually being at sea, away from land, is one of the things I love, as well as seeing new places.It's very peaceful.
