I'm TDY right now, and when I checked in, I was given a Non-A letter that covered the whole TDY (Dec to Feb), which the lodging people surprisingly gave me without any hassle. But I took leave for Christmas, so I checked out of the hotel. My question is whether I now have to check w/ lodging again when I go back, even though the non-A letter was for the whole time? I know you're only required to check once, but I didn't now if it's different once you check out and go on leave since per diem stops while I'm on leave (or at least that's what I've been told), or if the same non-A letter would cover both periods off base. Anyone had to deal with this at all? Thanks.
