Help me choose...Royal IOTS or Carnival Vista

Trying to decide between five nights on IOTS with stops in Labadee and Falmouth, Jamaica or the 6 night on the Vista stopping in Cozumel, Ocho Rios and Grand Cayman. We are a family of 6 with 2 kids ages 7 and 10, 2 adults and two grandparents:)

If price is comparable, six nights always trumps five. EM

I love Grand Cayman and the Carnival Vista is new- so I'd go with Carnival.

Thanks for your response.

Thanks for your response. The Independence is a bit cheaper but we are losing one night. So we'll have to see...
