We are looking at our first Disney Cruise for this October (Halloween week). It would be me, my wife, our 3 y/o daughter and 1 1/2 y/o son. We are split between the 5 day Magic western caribbean cruise in a Concierge 1BR suite and the 7 day Fantasy western caribbean cruise in a 4A deluxe family oceanview stateroom with veranda. Any advice to help us make up our minds?? Thanks!!
