Most of the people who flew were from out West. They were able to take all of their required uniform items such as NWU's, khakis, Dress Whites/Blues, etc. Not everyone had to leave things behind, but a few left behind PT gear, hoodies, and other issued (free) items you get at OCS for inspections, etc. I ended up just packing EVERYTHING in my car because it was either haul it down to my car, or an equal distance to a muddy dumpster (old Nimitz). And yes, in my first post I should have emphasized my car was packed full on the way home from OCS.
I too thought I would use my POV for storage while in OCS. But in our particular case, we weren't allowed to even go to our POVs until week 9. At least not to take/bring any items to and from. Due to the horrible weather, we were allowed to start and let them run a few times. In my 3 months nobody got liberty before week 9. You'll get NEX runs before week 9, probably in week 3 before RLP. The only thing that was in my car was a buddies backpack, a mostly empty suitcase I used to store my civies for the drive there, and a car cover that never made it out of the box. You will be able to store extra stuff in your suitcase aka "luckybag" in the luckybag room. You can access that periodically depending on class team. You have to wear your khaki's out on liberty, so you already have everything you need to go out.
If you get orders to FL they will be TDY, unless you're married. You will get 4 travel days given to you, after that you will have to use your leave days. Driving around and seeing some different cities would be fun after being tied down for so long, but for me I just wanted to get home and see family/friends for a few days. You'll graduate on a Friday (I believe), and you can leave Newport as soon as you get your orders. For us, it took until like 1500... I've heard the CO has changed that and FL bound Ensigns are getting their orders well in advance. So basically, you could graduate and drive 2+ days home, or go to the airport and be home that night.
Idk, there's really no wrong way to do it. You'll be paid for your plane tickets or your hotels/gas/food. The travel check was pretty generous, more than what I used on the way there. The drive for me was uneventful, and like I said I would have rather been home on graduation night rather than sleeping in a hotel along some Interstate in PA. Another factor for me was that I had to go back to IL to get the rest of my personal belongings. So I drove from RI, to IL, then to FL. Some people went straight down. Another side note, some people "hitched" rides down to FL, and they ended up purchasing/leasing a new vehicle here in FL.
