Thanks so far. Here's what my itinerary looks like; maybe I'd only need the single entry:

1. Fly from Germany to Sharm, connecting in Cairo (I assume this is where I'd get the visa) on MS.
2. Fly from Sharm back to Cairo on MS and overnight at an airport hotel (I assume I don't need another visa as it is a domestic flight?)
3. Fly to Jordan on MS.
4. Fly from Jordan to Germany later in the month on MS, transiting through CAI (I assume no separate visa needed as no need to enter Egypt proper).

I'm looking at a fairly good deal on MS, and obviously don't want to fill my passport up with visas if not needed. The only thing is, with Sharm having a slightly different entry status than the rest of Egypt, it is a little confusing. However, paying $30 instead of $15 is really no big deal, either.
