Avoid Eid and local holidays if you can and want to.
We both had a good and reasonably relaxing time at the Abu Dhabi Intercontinental, but we felt that next time we return there we will avoid public holidays.
We are both in our late 50,s, and the
noise levels and bustle at mealtimes was just too much for us personally. We have suggested to the hotel to set aside where possible adult only areas in the restaurants.
The hotel itself is very good and all the staff we met were helpful and courteous especially the restaurant staff, we both admired their patience and diplomacy. Quality of food and restaurants is excellent and the room we had was very clean and spacious.
There is some construction work going on nearby which you can see and hear from the beach area, but I didn't find it particularly obtrusive.
We would definitely return for an holiday, but definitely away from public holidays. [Less]
