Hi Sonia,
If you are planning on visiting in 2011, I'd encourage you to make your plans quickly since the holidays at Walt Disney World fill up quickly. If you are visiting in 2012, you have plenty of time to make your plans!
The first place I'd contact is a Grand Gathering Planner who can help with larger groups (guessing this is the case since you are having a family reunion) by calling 407-WDW-PLAN to answer your questions.
Then I'd encourage you to begin some research in three areas, beginning with the resorts by clicking
here. You'll find there is a wide range of resorts to fit everyone's budget and needs. Next, I'd begin looking over the different dining options in case you'd like to make some reservations for some table service restaurants and to look over the possibility of the dining plan by clicking
here. And finally, you'll want to look over the various ticket options to see which best fits everyone's needs by clicking
here.
All of these decisions can be overwhelming; please don't hesitate to ask more questions. We are all more than happy to help with all your questions! --
Kara
