I am going to WDW in Feb 2008 with 9 people. We are at 2 different hotels (SSR & POP). I already have my reservation but the other half doesn't have theirs yet. My question is: Can I make ADRs for our whole party now under my reservation even though they haven't made theirs yet? 
Edited to add: We are all planning to do the Dining Plan so does that make a difference? There are 4 of us on my reservation with the Dining Plan. Does that mean I can only make reservations for the 4 of us? Would I ever be able to make ressies for the 9 of us even if they make the hotel reservation since we are in seperate hotels? Thanks so much for your help.
