hi there,
Cruise ship sickness is one of the major concerns. If you're on a cruise for the first time, you'll usually feel nausea symptoms accompanied by headaches or other discomforts like stomach aches.
Motion sickness does get better after a couple of days on the cruise, after which time your body adjusts and the cruise sickness subsides.
If you find yourself experiencing cruise ship sickness, try to drink as much water as this will help with the nausea and cruise sickness.
Health Insurance is also important so make sure you purchase yours before you set sail. It is a good idea to check directly with your domestic health care provider to find out whether or not your insurance will cover you while traveling.
Hope this helps
