We are bringing guests on an upcoming visit. They may not be staying as long as us. Will we be able to get the DDP for all of us anyway? If so, how will that work? Will they, for example, get it for 7 days if they only stay 7 days, and us for 9 days, if we stay 9? Or, will we have to get 9 days for everybody even though they may not stay the whole 9 days? Not sure I'm being clear in this question... We are trying to talk them into staying the entire length of time but are not sure that will happen.
