If I take the entire family, I will have three seperate rooms. DS and his 4, DD and her three, and DW and me in third room. If I buy each familt a DDP they will each have the plan on their room key for their family. If my DS takes his wife to dinner one night and I take his kids (gaes 3,5,7) will I have access to their DDP credits or will they only be on my DS room key? We were going to try and give each of the husband and wife teams a night out, but was not sure how the kids would be able to use the plan without the parents along.
