Hi Susan,
I think you're asking about packages for a family or group with more than four members. Packages for travel to the Walt Disney World Resort start with four in the party because that is the standard occupancy for hotel rooms. Several of the resort hotels at Walt Disney World can accommodate more than four people. I found some great information on this web page,
Rooms for 5 guests or more. When you are pricing a vacation on the Walt Disney World web site, you can add the number of people in your party and receive pricing specific to your situation. Special offers available can be a value for a variety of family sizes.
If you have more than five in your family and are thinking of booking more than one room, you might want to call (407-WDISNEY or 407-934-7639.) You can book two rooms online, but in my opinion, it's easier to have them linked together when you call and speak to a representative.
If I misunderstood your question, or if you have any other questions, please let me know so I can help you plan your magical vacation!
Wishing you happy planning,
Amy H
