The Internet access on Carnival is really expensive, that is why people look for restaurants ashore with free Wi-Fi.

In Puerto Rico, a place with a really fast and free Internet access is Starbucks. It is located maybe 300 meters from the ship terminal.
We found Starbacks easily, bought some beverages and searched for a place to sit. The restaurant was packed with people addicted to the Internet. Fortunately, we had a chance to check e-mails and send some messages home.
