Not sure about you but ive definitely noticed an increasing trend of people considering local islands in the last 6 months with 2013 prices being published.
More and more people are asking about such places to be able to afford the Maldives. They seem to be be becoming very popular and would explain increasing day trippers to islands such as Biyadhoo so people can do some sunbathing and head to the bar.
Sitting on the fence you could argue that its one way of people being able to afford the Maldives (and probably bring some much needed dollars to local communities instead of going into the coffers of the large corporations) but then its could be tarnishing the reputations of resort islands by allowing large amount of day trippers on to places where actually, the infrastructure will not support such visits. I mean when Biyadhoo (or any similar small/medium island) is fully booked, its fully booked in terms of rooms and the island's ability to support those guests. Then allowing on an unspecified amount of additional people is bound to overload the system.
