Recently booked the Sky for February of 2012 with the sale. I know exactly what free gratuities, and free drink package are. Trying to figure out exactly what free WiFi gets me. This is my first "medallion" cruise. I assume the medallion does not require a separate WiFi, or not many would use it. Is fre WiFi only so I can use the medallion app on my phone? Free WiFi does not mean internet, correct? I still am encouraged to be on airplane mood while on the ship to avoid $$. In a nut shell---exactly what does free WiFi get me?
