Cruises aren't my cup of tea either but my sisters love them. Having only a few hours in each place is really not ideal. If you need to catch a bus or train to another town cuz, you catch an earlier return bus or train to make sure you get back to port in time. Then you catch the bus/train before that one in case there are delays or you miss that one, so all in all you make so many allowances that you're only left with fraction of the time 😄
This cruise was back in March when we were just coming out from lockdown and my sister found a very good deal. I figured it would be less hassle and an easy way to gradually ease back into travels. Hopefully will be back doing proper travels next year.
