We took the train to the Palace. It was a rainy day, but since most of the time was inside, it wasn't a huge bother. Great audio guides and really great rooms. All of us (wife and I and our two children -- 10 and 12) loved it. The maze isn't that big, and only takes about 15 minutes. The gardens weren't in bloom while we were there, but I would think in the spring and summer, this place is even more amazing.
