We usually book an SZ guy. Abit cheaper than SS. Due to the fact that there are very few SZs the odds are you will end up in an SS. We have always ended up in SS and currently on Grand Africa ended up in an SS. Midship. Deck 6. Which we prefer to deck 8. We are sandwiched between 2 decks of cabins, very quiet We have heard complaints about furniture being moved on 9. And we had actually more than once seen flooded cabins under the pool areas during storms
