I can also add this about the location,
Yes, it's very far out on the palm, even after Atlantis. So if you want to be closer to the shopping malls and metro, yes, then other properties could be a better choice. However if you're here on holiday and want to enjoy a resort with lovely beach, nice restaurants and relaxed life, then Waldorf is a great choice.

To compare Conrad and the Waldorf is to compare apple and bananas. Conrad is a more of a business hotel and there is no beach there. For me that loves beach life on holiday Conrad is not an option.
