The young and the young at heart will get a kick out of Carnival’s Seuss at Sea, a playful experience that brings the author’s beloved children’s books to life through parades, interactive story sessions, DIY activities and even a delightful Green Eggs and Ham breakfast. Let Thing 1 and Thing 2 be your guide while you set sail for destinations such as Canada, New England and the Caribbean, among others. This offering is available on various Carnival cruise ships and will soon head for Carnival Horizon. Naturally, such a wonderful journey deserves a spot on our best family cruises list!
