wigs, I agree that Soneva Fushi is more private, but as I recall it was situated on quite a large island, and when cruising the atoll, I remember it took at least several hours by speedboat to get to that area from Kuda Huraa. Probably a helicopter is the way to do it.
When were you there (FS on KH) last? IMO, the best season is the 'shoulder' in May as the Maldives head towards the low season during the monsoons. The room rates at FS fall to US$4-500 or so, but better yet, the occupancy rate drops to almost single digits. For all that, you just have to put up with perhaps a 20-minute shower in late afternoon.
