Covid is definitely alive and around. I got it on my Alaska cruise last month. Luckily it happened at the tail end of the cruise and I did not test + until the day I got home.
When real emergency occurs and panic sets in, I wonder how many passengers would actually remember what was said at muster and where they are supposed to go.
We all know where lawyers interest lies. They are a self serving, for-profit business, nothing more. In this case though, it sounds like Carnival just wants the incident buried and everyone involved to go away. One has to wonder why.
Lawyer can request the incident report and video of the fight from Carnival to find out what really happened. If you have a better idea? Let's hear it.
The advantage of booking at the dock on arrival is you can gauge the weather and decide if you want to spend the money on the excursion. The price is pretty much the same. I would not enjoy going to the glacier in pouring rain or on a cold windy day.
The train eticket and meeting time/location would show up on your Navigator app. On train excursion day, a staff would scan your sea card at the dock meeting area and you are good to board. No paper train ticket needed.
I had a few crew members and restaurant management who came up to me and asked if everything is fine and if not, be sure to let them know of any problem. I am perfectly fine with that kind of questions.
I got off Volendam last week. Hardly anyone washed their hands or used hand sanitizer anymore when entering buffet or MDR. The filling of personal drink containers without using a cup was also back in a big way. Definitely worse than pre Covid days.
