Hi. Stepherella!
It takes a while to get used to things being "free." Our first cruise, we were sitting in the theater waiting for the movie to start. Some folks came in with pizza that smelled wonderful. One of us asked, "I wonder how much that costs--it smells so good." Then we realized it was FREE. All we had to do was go get some.
Just remember--never let yourself get full. There's always more food on the way, and it might even be better than what you just ate!
