I am sure that you will have a wondeful trip.
If you are like me and have a lot of electronic gadgets to keep charged take a light weight electric strip to multiply the two outlets on the desk area. As you will be travelling in a very humid area keep your camera and video in a plastic bag when in the air conditioned room.
The food and entertainment wull be first class and the staff wonderfully kind, cheerful and helpful.
Read some of the cruise reviews on this site, they will give you lots of information.
Have a great experience.
