Thinking of cruising the Caribbean, but you're on a budget? At the agency where I work, I have lots of people asking me which cruise line is the most affordable, and what the big difference is between each line. I find that people may even write-off cruising, simply because they are overwhelmed by the many cruise lines to choose from, or because they're under the impression that cruising is not within their budget. However, there are many cruise lines that are affordable and ideal for young travellers. Even though these doubts still exist, more and more people are choosing a cruise over a typical all-inclusive resort vacation, and for a good reason.
