i thought id tell evryone what seed i used so here it is : Artomix

Incase you want to make a survival island map:
you spawn right on a medium size island. what i did
was flatten it out and out a layer of sand over the top.
it has the desired effect for a survival island only thing is
there is alot of landscape around.
to stop people from wondering off into the landscape i made a bedrock
wall 3 blocks high all the way around the island and made it a rule
not to pass the wall and that seemed to do the trick.

if you wanna see my survival island heres my post:
