Hi
From what I understand (I havent experienced this yet, as we are trying to do this for next year) you get special discounts for booking more then 8 people. So far this is what I have read....Again I havent experienced it yet, so I cant help you there..
Grand Gatherings (Groups of 8 or More)
Walt Disney World has created a program called Grand Gatherings, which is designed to provide special opportunities for groups traveling with 8 or more people ages 3 and up. (Babies under 3 can still come along, of course, but aren't counted toward the minimum number of people required to participate.)
Grand Gatherings offers special benefits and one-of-a-kind experiences that may not be available to smaller groups attending Walt Disney World. As part of a Grand Gatherings group you will have the option of booking special events with your group. These include:
International Dinner and IllumiNations Desert Reception
Safari Celebration Dinner
Good Morning Gathering
Magical Fireworks Voyage
A Grand Gatherings group can book one of these special events, or all of them. Experiences will be shared by multiple Grand Gathering parties.
There are also custom events that can be arranged for your group's special needs, including dinner parties, behind-the-scenes tours, group photographs, spa experiences and golf.
Choose your resort hotel. In order to qualify for a Grand Gathering, at least 80% of your group must be staying on Disney property. Guests not staying on property or at a Good Neighbor Hotel cannot participate in Grand Gathering events. You can select one resort or several to suit the individual needs of your group, and you can book the rooms as part of a package or as "room only" reservations.
Use a
travel agent. By using a travel agent who specializes in Disney, you can make the most of your money and time, allowing them to coordinate everything for your group. They can also do additional research and bookings for you.
