My DH & I walked through the SAB pool area to get to Beaches'NCream when were there this past December. It was so cold that day that we could hardly see the water for the stream rising. I counted 3 people in the pool (all young children, LOL). The life guards (and the 2 adults that I assumed were the parents of the swimmers) were wrapped in sweat pants, jackets and a blanket or two.
On our way back to the BWV (we were again cutting through the pool area), a CM chased after us to ask if we were YC/BC/BCV guests and if could he see our Resort IDs. He had a handful of wristbands. I guess not too many people cut through the pool area, because he gave us a funny look when I explained we were just taking a short cut. We both had on long pants, jackets, gloves and hats, so maybe he was really security - it was pretty obvious we didn't belong in there!
Anyway, even on a day when there was PLENTY of room in the pool and LOTS of empty deck chairs, they were enforcing the "guests of the hotel only" policy!
