Bonnie, are you keeping a list. I just did a quick count and it looks like we have 53 adults and 29 kids cruising from the DIS. That's even more than we had for the SS Member Cruise!
DH and I organized the meet for that and let me tell you it wore me out a bit (but in a good way). We did up buttons for everyone and ended up with 30 some bags of buttons (we had a lot of couples and very few kids on that cruise).
I love Peter's suggestion of Palo's brunch for everyone. Peter do you know who was able to set it up ahead of time?
The Deck 7 aft area is also great - especially if it is while cruising. I found on our May cruise last year that it can get very hot out there when the ship is docked, but I think it would be nice while the ship is moving (which it would be Sunday morning).
Have you thought about having a deck 5 meet on Saturday for those with kids (I'm saying Deck 5 since that is where the club and the lab is). Maybe at 3pm or so (after lunch but before the drill).
I agree that a mini meet at Sailaway can be fun - just wanted to let everyone know it can be hectic - especially with so many people. You see other people think they can use the same area

I even had one person come up to me and ask me for one of the buttons we had and she didn't know anything about the DIS - just wanted something free!
To any of you getting in early the Radisson is a great place for a mini meet as well. We did that out by the pool. It was a little cold, but still fun. Should be much better in May. We're flying in the morning of the cruise so we'll miss that one
Well enough rambling - its getting late. Just wanted to share a few thoughts.
