I was just afraid that I would not be able to get four rooms even tho I have the points because that is such a busy time of year.
The timeframe you are looking at isn't extraordinarily busy since the points are higher than Adventure Season. The first two weeks of December are extremely high demand due to the low costs, but rates start to go up after the 15th.
As long as you have the points you should be able to book. Just make sure you're prepared to call the morning that your 11 month window arrives (January 18th.) No sense waiting if you know the dates you want.
As some of the others noted, extended family are pretty notorious for canceling on short notice, not budgeting properly for the trip, expecting you to plan out their every move (or just let them go their own way) and generally not realizing what it costs to vacation at Disney or how much you are spending for the trip in the form of your
DVC purchase and annual dues. Sometime over the next 2 weeks I would
strongly recommend that you cover some of these items with
everyone involved:
1. Explain to them what they will have to pay for the trip. (Air transportation, Park tickets, Dining costs, Souvenirs, Recreation, etc.)
2. Discuss how everyone plans to interact during the trip. Everyone touring together? Going their own way? Visiting waterparks? Visiting DisneyQuest? Getting tickets for
MVMCP?
You'll need to know that in order to plan a basic agenda and book ADRs--which you are virtually obligated to do at 180 days. The ADRs will be exceedingly difficult to alter for that size group so you need to figure that most of your trip will be set in stone by June.
3. Make sure they realize that it's going to cost
you a lot of money (perhaps lose points) if anyone backs out down the road. Relatives have a way of not understanding the timeshare concept, apparently thinking that the accommodations are magically free and nobody will be hurt when they casually announce over Thanksgiving dinner that they've decided not to go because airfare is too expensive (or the kids can't miss school, or it conflicts with an office Christmas party, or any number of other lame excuses.)
4. Cover other basics like how DME works, arrival times, departure times, who is staying with whom, the sleeping accommodations in each room (going to have lots of sofabeds for that group), how big Walt Disney World truly is (lots of walking), what the weather is likely to be then (cold at night, can be very cold during the day, too), and so on.
Don't just go into this on a wing-and-a-prayer and just assume everyone will eventually get on the same page.
Good luck!
