8. Disney Cruise Line

Disney may offer rather expensive high-speed internet through Connect@Sea, however they also have an unusual feature:each cabin comes with two complimentary Wave Phones, which let you text and call any shipboard, stateroom, or Wave Phone onboard (and at the line’s private island, Castaway Cay). 

What it Costs: Disney Cruise Line does not offer an unlimited plan, and you'll pay for the data you use, not by the minute (which adds up fast). Prices start at 25 cents per MB, or you can opt for one of three packages, $19 for 100 MB, $39 for 300 MB, or $89 for 1000 MB. Multiple devices can use the same package. Wave phones, however, are complimentary and use is unlimited.
