I know how it feels. Before the COVID, we did 3 cruises (Mediterranean, Scandinavia, and Norway/Iceland) that my uncles and aunts (all in their mid-80s and do not speak English) joined us. Those were the most stressful cruises. On one cruise, aunt took off on her own to take pictures and didn't return to the meeting point on time. We spent over an hour going back and forth between 2 sightseeing points before finally found her. One another cruise, while we were in the Vatican, one aunt (in her late 80s) fell down over 30 steps of stairs. Had ambulance came. She was able to walk and insisted to return to the ship. Then went to see ship doctor, etc. Very messy situation. That was definitely the last time I will let those 4 uncles/aunts join us on any cruises. Just too stressful and too much responsibilities.
If you don't mind, I have more questions on Otaru.
This will be our first time visiting the Otaru port. Ship will be at port from 8 a.m. - 6 p.m. Do you recommend we visit both Sapporo and Otaru or just stay at Otaru? If just staying at Otaru, enough things/places to do/see for the whole day? Thank you.
