We had a group of 30 at OKW and it was magical. Don't do it all together! We had one big family dinner and one big family breakfast. I was the biggest "planner" so I made an itinerary for me and my DH. I then shared it with all and those who wanted to, joined up. Most days we had about half the group together at any time. The last day we took a family photo with matching shirts and then all went to a park in them. CMs were making a big fuss over all the matching blue shirts all over the park. Need any info/advice let me know - timonT  208.0 #23 3:54PM

We had 10 at our last trip. The only thing that we missed was WDW had just stopped doing the Grand Gatherings 2 months prior. We broke into smaller groups than designated certain meal times or events as group gatherings. - Grumps10  6.8 #260 12:07PM

We had 13 one time! My in laws, my parents, sister and her ex bf, brother, other brother and wife and my 2 nieces. My husband proposed to me that trip too!! It was DL's 50th anniversary year :) the trip was interesting with other things that happened but still a memorable one :) - brodysmommy  243.7 #1063 3:10PM

Wow. Happy planning. You can make it happy. Just don't feel you all have to do everything together. My sister and her family were there last August it was the best decision to stay in the same hotel not the same room lol - 5disneylovers  341.2 #11 5:38PM

Thanks everyone:). We are super excited. We are going to plan a few dinners together, but our big kids (ages 22-19) will be off on their own doing adventure rides while the little kids (ages 8-11) will hang with us "old people" :) - dragon16025  3.9 #550 9:46AM
