First consider how much port time available then subtract at least 2 hours travel time to and from port. If you use Disney bus, they only go to airport or resort at $35 per person one way in the morning. That does not take into consideration that they only leave when the bus is full and make stops at multiple resorts. Return to port will have to use other means as Disney resort transport for folks going on cruise leaves around noon with pickup at multiple resorts. I can't advise on ticket price because that will depend on day and park chosen but plan on worst cases scenerio around $150 per ticket for each person in your party without hopper upgrade. Then trying to figure out fast pass and ADR will be a challenge without set times. You might consider Disney Springs or going to a resort visit to cluster of resorts such as monorail with GF, Poly and Contempary to ride monorail and you would have pick of ADRs. Another cluster would be BWI, BC/Yacht Club and Swan/Dolphin. You could take boat ride to Studios or ride the Skyliner to other resorts. If you like to watch animals head to AKL/Kidani. Again you would have a taste of Disney and several eating options at each resort. Best of luck in your planning.
