I would assume there will be other appointees in the position as yours so there will be plenty of people going that way.
Pretty sure the AOG provides transportation to the Doolittle Hall (AOG building) for those appointees doing the AOG Bed & Breakfast program.
Highly, highly recommend that program -- and should still be able to sign up for it on AOG site. Small fee for it - but not as much as a hotel -- and the host family will pick up your child at either airport or AOG building, take them home for the night, then bring them to in-processing in the AM.
