I am a little late to this, but you might want to consider internet cafes or access points in the port of call. I tried on board access on two cruises and gave up. I now look up the location on land side access and use it while in port. Canadian ports on the Atlantic side almost all have pretty good free access points. Even in Alaska I found Internet cafes for about $5 an hour. Cruisecritic gives internet options in their reviews for ports of call. PEI is an example.
