Wanted to provide an update for anyone else that is in a similar situation. I ended up waffling but decided that I did not want to spend the time going back and forth form the hotel. The airport is very efficient. I applied for an e-visa online (free). You have to go to the visa issuance area on arrival and I was issued my visa within 10 minutes. Passport control and baggage claim were quick. The landside area of Terminal 1 has lots of shops (including Debenhams) and multiple coffee shops with good wifi. The airside area is much smaller than other large middle eastern airports but there a few places to eat and ample areas to charge your device. It was overall quite easy to spend 6 hours here. The caveat is that I am jetlagged and so was awake for the whole time overnight and I think a hotel would have made more sense if I was tired.
