Just looking outside the box is all. Maybe Joran did leave her on the beach and she walked back to the hotel area and something went awry then.
Who was sharing a room with Natalee at the HI? I don't understand why they wouldn't notice if she didn't show up in the room that night/early morning?
Hmmmm...that one doesn't do it for me either. The beach in question is a long way from the HI. It would seem even longer at night when you can't see it so well. Also, you're not taking into consideration of how they would have 'disposed' of her in the short time they had before leaving. Disposed of her so well that she hasn't been found yet. These are not island kids with knowledge of the island or ready access to boats. If someone from MB did something bad to her then someone from Aruba is covering for them...I can't make that add up. Sorry.
