They definitely have lifeguards, but I'm not sure about swimming devices. I know there are several pools all around the "big" one, and even the big one has different areas to it. One area of the big pool is like a beach with sand and very shallow. I know I've seen very young ones in the pool; I just can't remember if they had wings.
Make sure you stick your head under the water to hear the tunes!
I'm jealous. I just bought a timeshare off property, so I'm afraid my HRH stays will be limited from here on out. Awesome hotel and atmosphere. Hope you have a rockin' good time
