Alias,
I went to Maldives last sept and stayed at Medhufushi Resort, which requires transfer by sea planes.
Had to stay one night at Male as well, due to the operating hours of the sea planes. I personally think that there's not much of a difference whether you are staying at Male at one night (for those resorts that require sea plane transfer) or get transfer to the resort (via speedboat) on the same night....
Since the timing u reach Male will be pretty late like 9+, by the time u check into the Male hotel, just in time for a good night's rest... got to wake up quite early on the next and catch the early plan to the resort after breakfast...
hope this helps.
