hi everyone. i am going to wdw in about 3 weeks with a friend. we are staying at por for 6 nights. another friend of ours may be able to come down for 2 nights. does anyone know if i have to add the person a certain amount of time in advance or can i do it a day or so before we check in? i know we will have to pay a little more but i have no idea as to when i have to notify them of the extra person. thanks for any help!
