My father took a total of 12 of us on a cruise to Haiti, Jamaica, Grand Caymen and mexico.
It was a nice vacation, especially since no phone service kept everyone talking to each other and being on the ship we all got loads of face time.
IF you are very bored and want to see what some of the ports and ship looked like, feel free to peek at my Flickr page.
