I agree with Olivia. I would do the Whisper hands down!!! Newer ship with much larger cabins. Also because the ship is larger, with not that many more passengers, you have a much larger space to passenger ratio. Also love the relaxing sea days. We are going on the Whisper in 4 more weeks in the Caribbean. We chose this itinerary because that it has two sea days at the end of the cruise, and we will come home very relaxed.
That being said we have booked the Cloud for our Med cruise in April. It is because we could not find a comparable cruise on the Whisper.
