I went to dubai for ten days, but that was before this hotel/aquarium was open. However, everything about dubai is bigger and better than everywhere else. Which also means it is more expensive. It is also HOT. 100+ on every summer day. So, i am sure this is a very big aquarium, but that does not mean the husbandry, etc, is very great. The structures are probably fine, but when it comes to live animals, especially with large numbers of large sharks, i do not think they thought out compatibility very well.
