Oh yeah, living in base is nice. You'll have EWR to start with though (unless something weird happens). None of the lowest class right now can hold CLE, but you should be able to within a few months at the latest.

In my opinion, get the room. Ground is pretty thorough and you'll want to study with your sim partner as much as you can. Remember that by staying at home and driving in every day you may be potentially hurting not only your studying, but his/hers as well.

Plus when you get into the second week or so you'll want to hit up the paper tigers/FMS trainer as much as you can, and they can get pretty busy, especially if an upgrade class is running concurrent, so you'll end up in there in the middle of the night.

Oh yeah...and there are a couple things that are different from the memory sheet they gave us that'll screw you not so much in sims, but on IOE. Might be worth checking into.
