Ex Input:
Next Thursday near 9 AM, I might have to take a cab from La Defense metro station to go to a district which is outside the subway zone.

According to this PDF file (in French) about Paris La Defense (page 4) and this map, there is a taxi station at La Defense not far from the metro station.

Google Street View shows the station, and there are five taxi cabs waiting, but there are only one cab from another point of view. The other lane is empty. This is scary.

Are there cabs available all the time there, or do I have to book a taxi before arriving at La Defense? If I have to book it, is it better to do it a few minutes before arriving, or should I do it the day before my trip?

After being at La Defense for five consecutive times near 9 AM and 9:30 AM, I confirm that there were always a lot of cabs available (always at least five, often more). I believe that this was also the case near 4 PM. Of course, the situation may be different on weekends.

If you look at GoSim's rates (or the rates of other international sim cards), you can see that it has both a US and a global number. What is a global number? Is it the number you dial internationally to call the US number? Then why are the fees higher for receiving a call?

If it is a separate prefix for these numbers, why can't I find any information about these numbers in Wikipedia's list of country codes?

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 :)
