Graduation right before winter break?

hey guys, my husband is currently in BCT and his graduation was going to be December 8th but his processing took an extra week and so his new graduation is set at December 18th. He said that it’s the absolute last day they can graduate before winter break, which means he would be able to drive back home with us for break before going to his AIT. But nothing has gone to plan so far so I’m wondering if this has happened to anyone else and if he’ll actually be able to leave with us after his graduation, or if he needs to stay that night and leave the next day? I also want to know because the hotel arrangements too. Any advice is highly appreciated!
