BBB advance reservation question

[Mambo Junkie]

We are traveling in October for the Halloween party. There is a huge group; 19 for my DIL's family, 3 for us, and 7 with friends. We are going to try to make BBB reservations for 4 of the girls (ages 8, 9, 10, and 10). Two are staying on-site, and 2 are staying offsite. I am on site and will be handling the reservations because most of them have never been to Disney before and I always do all our family planning. Anyway, my question is: will the offsite people be able to be booked at 60+7? We arrive on Saturday and aren't planning our princess day until the following Friday. They are already in my friends list and show up when I try to book now. I just don't want to be surprised when I go to book and I can't book them because they are offsite.
Thanks!
