The modern view is less bucolic. There's a wall and a freeway.

The pool's still there. I can't vouch for the King's Hideaway, though. It's present in Google Street View, but the hotel was closed, sold, and split up into two different properties with a late 2014 opening.

It seems likem the King's Hideaway would be a noisy place for meetings, no? Unless you meant "a place for the boys to get away and drink during the convention," in which case, sure, it's perfect.
