Don't Forget the Immodium. During our last cruise, day 1, I went to the infermary to get my dh something. This was very BAD, they quarantined him to the cabin for close to 48 hours. I went to our 1st formal night without him, luckily we were cruising with friends and they were very supportive.
So I must Repeat...IMMODIUM
Do not ask the infermary for assistance unless you want to stay in your cabin.
