FE- I'll make a sign up as it gets a little closer, say at 6 months? I would recommend closing it about 30 days ahead. I'll make a spreadsheet with everyone's info, and I will email the link to the participants (some don't want their kids' names or cabin number easily available on the Dis). When it gets time, I'll want the following information: Names of everyone in the cabin Ages of kids Cabin number Email address Food allergies/special requests (such as gluten free, no alcohol, etc) I'll also send out a map before the cruise with all the participating cabins highlighted, it makes finding some of the inside cabins much easier! I'm already thinking of my gifts!
