Malolo is a great family spot, lots for the kids to do etc. Not really suited for kiting, but definitely take some kit, you can get a boat out to the sandbar no problem and kite back to the resort.
I was there in Sept 2011 for a week with the family. Winds weren't great at that time of year, but I knew that and took gear anyway.
Got out for 4 sessions on Malolo and a couple on Denarue.
As mentioned, the beach is very narrow at high tide, sharp rocks, shells and coral to trash your gear.
I self landed / launched by tethering on the other side of the jetty in front of the staff quarters, away from the guests.
Be careful if the wind is on the lighter side and you head offshore a bit (depending on wind direction / tide flow), as the current is quite strong and you can easily find yourself downwind of the northern tip of the island. I headed offshore a fair way on my Zephyr and due to the current, before I knew it was a long way downwind and almost never made it back

. Ask the water sport guys to keep an eye on you, I guess they would come rescue you if needed.
