Ed,
Give me a break man! After all those posts you have made, you finally state that you meant Legends is flooded by "people"? Well if that wasn't a rather misleading statement that could have been corrected in your first reply but wasn't.
And I do remember the day Legends opened, I was there back in 1997 and took a picture of the beach.
As with any concrete structure on any beach, I personally think they tend to build them too close to the sea line. The sea seems to not like concrete structures in its way. The sea wants to roll in and roll out naturally and any concrete structure inhibits that desire.
Over the years, the beach did expand for a while, then receded for a while, and it has been repeating that same pattern since the day it opened.
Here are two pictures the first one taken the day Legends opened in 1997:
and then the one I took yesterday.
Although they are taken at different angles, I cannot say with any great certainty that the beach is substantially bigger in the 1997 photo or substantially smaller in the 2013 photo. There is the high water line which seems to be nearly in the same area, although it seems to be at a somewhat steeper angle in the 97 photo, and the new Legends sign wasn't even there in the 1997 photo, but now sits before the concrete dining area which is not visible in the 2013 photo.
And before you say I edited the photo back in 1997, you can check it yourself on the WayBack Machine at archives.org - search for any date in 1997 after May.
The bottom line is that you admit that Legends is crowded, very crowded. That would tell me that they must be doing something right. If it is as bad as you claim, why would people simply not walk over to Tamboo or Kuyaba which are right next door?
