ILL reservation time for group

Do all members of a group booking an Individual Lightning Lane have to be a WDW hotel guest in order to book at 7am? I’m in a group of 6 and will be staying at the Boardwalk, but 2 in the group are staying off property. Can I book the reservation for all 6 of us at 7am since I’m a WDW hotel guests and booking for everyone with a linked account, or will the 2 people staying off site be excluded from the reservation and be forced to book at park opening time? Thanks!

You will not be able to get ILL at 7am for the 2 members of your group that are offsite. They have to wait until park open.
