We have an 18 hour layover beginning of November. We arrive 19.40 and depart 13.45 next day. The grand mosque is a must see (in the morning after 9am when it's open) although would've been nice to see at night lit up too. We don't mind a 'dry' hotel if there's a bar nearby or a shopping mall would be good to get some fast food the evening we arrive and if we could see some of the cornice too. We'd just have hand luggage I think as flights are Etihad so think luggage should go straight through. So we'd probably be best getting a taxi everywhere (although we're happy with buses if they're regular) and not sure if we can do the mosque on the way to the airport if we took our hand luggage with us, or whether we'd be best returning to the hotel. We've looked at Ibis gate, Millenium (has a good offer on) and centro al manhal by rotana. We just want a comfy bed and quiet. We're happy walking anywhere that's practicable.Any suggestions or other recommendations are appreciated as we want to maximise our short time as well as getting some sleep! Returning we will just have the evening as fly back home to the UK at 10am. Thanks.
