I agree it probably is a little bit small for the resort.
we never saw any ducks and certainly didnt have any issues with it not being clean. The slide is tame, but my 10yo & I both went on it and loved it.
A pet peeve I have, Just like anywhere that has deck chairs, people still dump there towels to reserve. It is one thing that annoys me about any pool. I wish Disney had a system to make it fair for everyone.
