We brought noodles into that pool during our August 2005 BWV stay. CMs didn't say boo about it, so those appear to be O.K. I don't know about inflatables like tubes or floats (have never seen them in that pool during four different stays at the resort).
Thanks!!! That is good to know you can bring your own toys. DD (2) likes her small inflatable ring that helps her swim and I also have a ring with a seat that I use for DS (1) It helps a bit when I am swimming with both kids by myself since they are both so young and can't swim yet.
We had exactly the same thing happen with boogie boards at DVC Vero Beach last week!! A nice guy gave us two on our second day because he was checking out, and we passed them onto another family on our last day.
