Im going on the royal Caribbean soon to Mexico and i have a 3G ipad so what should i use?
International plan: $24.99/month: 20 MB Data Global Add-On for 30 days
$59.99/month: 50 MB Data Global Add-On for 30 days
OR
cruise ship's wifi: $.65 a minute or a package plan; $28.00 for 60 minutes
$38.00 for 90 minutes
( i need to go to some parts of the ship to get wifi)
Im listing only those because thats my money limit.... Im gonna use it for internet web surfing like Facebook or Macrumors (ofcourse
) and Itunes or app stores....im going in 6 months so if the new ipad comes out b4 that ill get that and if it has a webcam ill use oovoo (video chat) so what should i use... remember if i get the 2nd gen ill use the video chat.... so whats best for me???? 


EDIT: should i use it by time (wifi on boat) or should i go by MB size (3g)
