As a first time cruiser on
DCL, you will probably want to experience everything. Keep in mind you are on vacation and try to enjoy yourself.
One thing that we have done on our cruises that someone told us about is great if you have kids. Bring a pillow case, t-shirt, or blank frame and a set of colorful permanent markers (i.e sharpies) and leave it at the front desk and ask for the characters to sign whatever you bring. At the end of the cruise, they will deliver your signed item to your room with all of the characters signatures on it. It saves standing in line for character autographs.
