How good is the internet at sea?

Internet at sea will never be as reliable as on shore Internet is provided by communicating with a satellite by an antenna on the cruise. The antennas transmit signals from the ship to a satellite and the satellite then sends a signal back to the ship's antenna.

Data use onboard a cruise ship is ridiculously expensive, especially because it tends to add up quickly. Always remember to put your phone in airplane mode or turn off data roaming before you head out to sea and don't want to be smacked with a hefty bill upon returning home. Even in port, the rates get pretty high.

Medical staff varies by ship size, but typically ships have a doctor and at least two nurses. The world's largest cruise ships may have two doctors and five or six nurses. River ships and small ships that hover close to shore have less staff since they can easily access health facilities on land.
