Hello -
For our last grand gathering (2007) we had 21 people.
We found 'Ohanas and Chef Mickeys to be very family friendly.
My definition of family friendly is the ability to seat us all together - and also the overall atmosphere was such that we didn't feel we were too loud, and they had times when the kids could get up and let out some energy and dance during some of their skits.
We also enjoyed our dinners at LeCelier - even the kids liked the menu.
For our Feb 2009 trip I've made ADRs at Cali Grill, LeCelier, 'Ohana, CRT, Tutto Italia and Biergarten. One tip when making your ADRs: I found this year when I called group dining, they would refer me directly to the restaurant in some cases (LeCelier, Tutto) to make my reservations because of being a large group. Although it worked out ok for LeCelier - they never called me back after 24 hrs, so I called them the following day and got a very helpful employee to make the ADR for me. I'm explaining this because I found it's a pain to call different numbers and wait for call backs, etc. Finally I just decided to call back group dining on the rest and make split reservations (for example for Tutto I got a table of 8 under my name, a table of 8 under my MIL name, and a table for the remainder under my SIL name).
Sorry I've been kinda wordy on my reply, but just trying to pass on helpful info!
Good luck, it's challenging to manage such a large group, but it can also be fun doing the planning
