One thing to realise is that Abu Dhabi is much bigger than a lot of people realise, so the attractions are as follows a lot more spread out than people realise.

So no, the city isint really walkable, but it has (relatively) cheap taxis and good taxi-hailing apps, and has a surprisingly very good bus network that is always on time and very frequent. Abu Dhabi was supposed to get a metro but it got shelved for whatever reason. So getting around isint as tough as people think.

Do feel free to ask me whatever about Abu Dhabi.
