The Disney Cruise Line blog reports the Disney Cruise line will begin charging for actual data usage rather than by the hour. Rates will rane from 25 cents / megabyte for pay-as-you-go down to 9 cents / megabyte for a 1 Gigabyte plan. The new package rolled out today on the Disney Magic (and even lower introductory rates) and is expected to be on all ships by March 8th.
