Interesting. For whom was it a non-issue? For the regular guest capacity of the Magic or Wonder who normally fit comfortably on the old family beach, and now have an extra 150 yards of expanded family beach to roam? Or the 1600 additional passengers who are going to come off the Disney Dream in a few months and wonder if they are supposed to fit in that 150 yards of beach while 100 of thier shipmates stretch out on the other 150 yards of private beach.
Well, according to Disney's own press release from August (or whatever you call it), the family beach is being expanded by 700':

It's definitely much bigger and i cant imagine it being all private--it has to be largely "public" wouldn't you think? As an aside, it appears that there will be a back road to the cabanas, but for what I have no idea, because there was signage past the bike rental area on a road that said "welcome cabana guests". I wish I snapped a pic. Anyone else see that?
