True, the OP would not be able to use DME to return to the airport after the stay at SOG.I don't know if you were planning on DME for the trip in only, because I don't know if you could book it for the return trip days after you check out. I think you probably can't, but truthfully, not sure.
I believe that you can book FP+ for the day of arrival and the day of check-out at the 60-day marks with a 1-night stay (each day needs to be booked separately, not at the same time unless both days are inside the 60-day window). This would work as long as you have at least 2 days of admission on tickets that are attached to your MDE account.Yes, you'd get magic bands and be able to use MDE. As for the FP+ I'm not sure which day(s) you'd be able to make the 60 day mark for. Maybe someone else can answer that.
