i have never stayed at the w maldives but having stayed at the sheraton & conrad in maldives, i can safely say the conrad maldives is not only the best hilton property but also the best hotel i have ever been to in my life....you cannot compare it to the sheraton maldives....
both properties are expensive....food will cost more than pretty much every other place in the world....the conrad was much more expensive but then again the quality of the hotel makes up for it....
from male you have to pay around $420 roundtrip to get to the conrad & about $66 roundtrip to get to the sheraton....
the rooms are nice at both proprties....i really liked the overwater bugalows at the sheraton....but the deluxe water villas we stayed in at the conrad are out of this world....
if you have to money to spend then there is no other place like the conrad maldives....if not then the sheraton maldives is also great....
