We will be travelling to Disney early Sept. It will be myself, my husband, my son who will be 2, and my 16 year old stepsister who is coming along to help us(and because we love her). We will be staying at the Pop Century (we have stayed here several times, but it has always been just me & my husband , and once with our son. I want my stepsister to have her own room, joining with ours. I have done lots of research and discovered it is cheaper to do this: -Book one room package with all 4 of us (will include park tickets and hopefully the free dining plan). Book an extra room only with my AAA discount it is cheaper to do that than this: book one room package including tickets and DP for 1 adult & 2 children and another room/package for the other adult (because obviously they dont let you book a room for only one child and then we could just let her sleep in there) It is about $150 cheaper to do it the first way but am wondering if they will let us do it that way???
