Imagine this scenario: You book a two week cruise to the Caribbean or Alaska, get sick and end up sequestered to your cabin for the entire trip. While your fellow passengers are busy soaking up the sun or exploring glaciers, you're spending the day trying to find a channel that comes in on the staticy television set and reading (and re-reading) the ship's daily newsletter. You can't even go down to the movie theater to watch "The Bourne Identity" and for you, the midnight buffet will consist of room service sandwiches and luke warm tea. Let's face it: your dream vacation is ruined.
