You will be given a definition of a task first, then some input of the task.
Given a travel related situation, and given a specific question about the situation, summarize the question into a title

I'm planning on going to the caribbean (any part of it) during January 2012 (for 7 to 12 days) but anything above U$S 1500 per person turns out to be too expensive.

I'm basically looking for a whole package including airfare for that money, intending to buy for two people. Every suggestion comes in handy: cheap destinations, airlines, bugdet dining, etc.

Inexpensive all-inclusive cruises can be found to some destinations, but airfare is too expensive. Some examples: to Antilles, Venezuela and Dominican Republic

For cruises from the US I must raise a word of caution: for an Argentinean a visa is needed, which costs U$S 140 (besides, it's a pain to get :)

Output:
Budget caribbean in January from South America
