I'm actually in Maldives and will be at FS KH in few days (staying at soneva fushi at the moment) and will report about it.

Two years ago I stayed at Soneva Fushi as well and to O&O. As you see I came back to SF but not to O&O so I think that said everything about my opinion about Reethi Rha.
But do not missundertand me.... O&O is a great resort, It is just me that I'm looking for a different experience when in maldives compared to the one that O&O delivers....

feel free to ask for any additional information.
