Hi! I spoke to a friend of mine who went on the Disney Alaska cruise last year and here is what she told me about how they organized their FE list.
Basically their FE organizer posted a list just like the one DVC Family has already compiled (i.e. by DISBoard name) but included all of the information next to each participant -- for example, IFAM5, Cabin #, DW, DH, DS(9), etc.
My friend mentioned that sometimes cabin numbers change if people upgrade, etc. so I think their FE group met on the first day of the cruise and made sure of final cabin numbers at that time.
She also mentioned that it varied on how people "labeled" their gifts. She used her DISBoard name to "sign" each gift but others left gifts incognito as part of the fun.
Hope this helps!
