What is your age? The average age on my TATL cruise last year must have been in the upper 60s or even mid 70s. At early 50, we were among the youngest people (just one couple in their 20s). Your shorter TATL may well have a younger demographic.

As for weather, that's the great unknown. Could be stormy, could be calm.

As for typical day, wake up late, have a sit-down breakfast (or room service), maybe do an activity, have a sit-down lunch, nap, relax, read for the afternoon or do some activities, dinner, maybe show after.

Bear in mind that depending on direction of travel, you're either gaining or losing an hour of time every full sailing day.
