Had a great layover at the Doubletree. About an hour from landing to our room. Easy taxi ride, great new hotel just off the Corniche. Walked to and from the souq, a little warm at 7pm but fine at 10pm. A little shopping and a mediocre dinner was OK. A nice shower and a great bed was awesome! Caught a taxi on the street the next morning back to the airport.
On the return, we had 8.5 hours and did not feel like going into town. No free STPC so we sucked up the cost for the airport hotel. Started at $370 (no reservation), then down to $310, ended up at $241, about what it costs to book online. My wife and daughter were aghast that I was willing to walk away from a bed and shower - it was 11:30pm and we just spent 7.5 hours in A320 economy (ZNZ-JRO-DOH). Clean room, great location (obviously). We checked out at 7:00am for our 8:05 departure.
