If money is not an issue......out of these choices...go with Poly Lagoon.
But I think I would check out a 2 bedroom at Boardwalk or Beach or Yatch Club.
But it looks like you are wanting MK resort....
Then if you want to save a few more $$ go with Poly garden. It is nice to be able to have a lagoon view....but you can always just walk down by the beach to watch the fireworks, etc.
