Please add a warning that cruise ships (even in port) are not included in your normal data allowance.

There is usually signage of the rates for using a cruise ship network located on the ship.
You can turn off automatic network selection to avoid your handset automatically connecting to these types of networks when you're going abroad this way.
Our Inclusive EU Roaming list will display the inclusive countries you're able to roam in (which would not include a cruise ship network).
