Enjoy your trip!
There's generally a first 24hrs special for unlimited internet through the photo shop for $79. Still steep for 4 nights but it's the same price on a 14-night cruise. Generally fairly good satellite and local wi-fi performance. (And we want to hear how you're going!)
Oh, and also make sure you step out on the bow (as shown in the webcam pic) sometime. Access up a flight of stairs from the promenade deck forward (the inside bit) - nothing fancy but it's a place you don't get to access on all ships and makes it feel "real".
