... and as a bonus the quiet pool by the Treeshouses is usually vacant. We visited over NYE 2013 and only ever saw one other group using that pool. Every time that we used it we had it to ourselves.
We drove our car over to the Paddock area one day as we had not used that pool yet. It worked fine, but not sure it was really worth it. Something about driving back to your room in a wet swim suit makes it less enjoyable. SSR probably has the most pools of any DVC resort. It isn't difficult to use them from the THV's, but does take some effort.
My one pointer for the Treehouses is to request a location toward the path to the Grandstand (South end). When it's time to catch a bus to a park, walk over to the Grandstand stop instead of doing the THV transfer. Grandstand is the first pickup location for SSR so you will probably always get a seat. Same thing for the bus dropoff. Get off at Grandstand and walk back. It's more of a walk (not much), but is very much quicker.
