My husband used to be the pickiest eater I had ever met. Then, I got him hooked on cruising. Now, he ALWAYS orders at least 2 entrees, one that he knows he will like and one that he isn't sure about. Meanwhile, I order lots of appetizers, since that is my favorite part of the meal and 2 desserts. I am very picky about sweets, and I'm lucky if there is one that I like enough to eat.
SO.....order as many as you want. It is normal on cruise ships!
