This is an 80s, possibly early 90s, teen romance. A girl goes on a spring break cruise with her grandma. She has a crush on one of the ship’s workers. And also meets another passenger that is the “funny” boy. The ship’s worker leads her on a bit. One funny part is; she takes way too many tanning pills and turns orange trying to impress him. She ends up with the funny boy in the end. I thought his name was possibly Jace or something similar.
