Hi Mike!
This sounds like a fun trip that you are planning and the kids are sure to have a great time next year. I plan a big reunion at Walt Disney World every year, so I can give you some advice on how to tackle planning for your group.
I highly suggest reaching out to
Walt Disney World Disney Group Getaways. A lovely Cast Member can guide you on how to plan for a large party and work out a discounted room block if you'll be needing 10 or more Disney Resort hotel rooms. With a room block in place, your group will be eligible for discounted tickets as well as be eligible to add the
Disney Dining Plan. Unfortunately, I cannot quote you any pricing since it's all specific to what is available and what the needs of your group are, but I can tell you that working with the Disney Group Getaways team makes planning a group visit essentially seamless. This team can also help you plan any events if you'd like to add a little something extra to your vacation.
I'd also suggest checking out the
Disney Youth Programs. There are several programs and discounted ticket offers for group youth programs, including organized faith based youth trips.
I hope this helps steer you in the right direction for starting to plan out your trip. Please stop back by if you have any additional questions.
Have a magical day!
Leslie
