Don is going on a cruise and he wants to use Wi-Fi. Is SkyRoam good? Leo says no, not for a cruise. The best and cheapest way is from the cruise line itself. It's not cheap or fast, though. Royal Caribbean has super fast internet called VOOM, but it's still expensive. He'll have to get up really early in the morning to have decent speeds.
Unless he's in a port, he should just pretend that he's disconnected from the world. Then when he's in port, he can then use an internet cafe or get a prepaid MiFi card to handle cellular.
