It's no problem getting through the gate with Uber between 9am and 6pm. My son, who was there today for the appointee tour, did get through the gate before 8am with an Uber driver but he showed his military ID which, I believe, technically made the Uber driver his guest. He's not sure he would have been able to get through outside of the 9-6 hours without his credentials. If your child is heading in alone and doesn't have DoD creds, it's probably a good idea to talk to someone at USAFA ahead of time. The good news is my DS is ready to accept his nomination after the visit!!My son was told by USAFA that he could get through the gate with Uber bc he has DOD creds. I would think that an appointee without these might be able to show his or her appointee tour registration papers. His tour is tomorrow and I will let you know how the transportation goes.
