Internet Is Expensive
Expectation: In the midst of your excitement, it may occur to you that you need mobile service and that you will be able to obtain free cell service or have your phone connected in some way so that you can post images on Facebook, complete office work, or simply surf the internet.
Reality: The internet is slower and less reliable on water than on land. The internet on cruise ships is accessed by sending a signal 22,000 miles to a satellite, then 22,000 miles back to the ground. At the same time, most passengers would not require Wifi while onboard. Anyone who needs to work or even check their email will be charged $89 for 1000MB of internet.
