It's does look scary because it goes round and round, but it's not anything, really.
Just an aside - BWI pool is probably my least favorite resort pool. The whole area is very hotel-ish, rather than resort-ish. Does that make sense? I'm comparing it to AKL with lush foliage, or Poly/GF with the white sand beach and a view of the lake.
BWI - besides that dang clown head - looks like a thousand hotel pool areas.
