I can't answer that. I can only say for our DS as an AFROTC cadet on scholarship at a traditional university, he does not have a military ID except the one he has as a dependent through Bullet.
Our DS is a jr or aka C300 in AFROTC terms. I would bet SMI, such as VMI, the CAC as a PC (jr in college) is common place. However, attending an SMI is not the traditional route for the traditional ROTC cadet.
Again, I emphasize talk to the schools det during that hs sr yr and ask everything you can imagine, because it does vary from branch to branch, det to det.
Put all of that aside for the OP, the answer still comes out the same, spring break in HA using Space A air and hotels is a long shot. Not saying you cant do it, just saying, that like having a Plan B for the SAs, it would be advisable to have a Plan B for travel if you are on a limited time frame.
Let's pretend this poster is from NJ and can travel Space A. Here's how it works.
Friday Morning you show up to McQuire for an airlift to Kelly, Kelly than goes to Hickham.
He needs to get on at McQuire and hope he doesn't get bumped at Kelly.
He doesn't get bumped, and makes it to HA.
Now he has to get a ride out of HA back to NJ. Aircraft breaks down on Sat and he is stuck in HA until the next flight out on Tuesday, but classes start Monday.
Additionally remember Space A is a perk, the 1st job is military operations. Every time Bullet saw action as a flier, it was literally no notice.
Our close friend was in Germany (Ramstein) when Gulf I occurred. They left out of Mildenhall and got stuck there, had to train it to France, Ferry from France to the UK, train it in the UK, and than bus it back to Heyford.
In AK, where they have a MAC terminal, on Friday night we were hanging out at the club joking and drinking. 8 A.M. Sat and the phone rang, he deployed to Korea on Monday. Transports in the AF have a C or K...C130 is cargo, when the 90th went, so did support and they flew in the C130. That flight to Davis was canceled to take the 90th to Korea.
When he was an ALO at Pope, another heavy base, as we walked out the door for Church on Sunday a.m., the phone rang. I took the kids by myself and 6 days later he was on a C-130 headed for Haiti. The runway on Thursday was filled with Dover, Charleston, and McQuire heavies.
People in HA were SOL if they didn't have a plan B because planned flights were canceled due to missions.
Space A is great, but you have to be able to be flexible with no hard time line, it is hard to do so when you have 1 week.
FWIW, I also chuckled about Hawaii spring break. The Hale Koa is booked out for March months and months in advance because in AK at Elmendorf they have MAC, and March is when everyone is sick of snow so they plan their warm vacation. Hawaii is the top on their hit list. As AD members, who rank above cadets, they still have to plan 6 months in advance to get the spot.
My suggestion is if you have a military id, use it for discounts from the real world. I.E. contact the hotel and ask for a military discount. It not only works for hotels and airlines, but Aeropostale will give a 10% military discount off your bill, same with Rack Room shoes, and certain restaurants. Just ask when the bill comes do you give military discount? All you have to do is show your i.d. to get it.
