I'm going to reply to my own question in case anyone needs this info in the future. Basically there is not much of anything to do in the airport if you are going from international to domestic. Once you clear pre-security there are a few shops, same as before security. You will not be able to get into the main airport part as that is for International flights only. Free WIFI all over. Not really anywhere to sleep. Cleaning people will make you benches move around as they clean the terminal. We did not need to re-check our bags or check in again as we had boarding passes for the flight to Aqaba. If you can avoid an overnight layover here that would be the best option, but is is not the end of the world waiting around, we were fine to go snorkeling later that day.
