Dedicate at least two to three hours!
2 hours to view the art and read the information. A good way to start is take the time you have and use it to visit and read about the art you like. You can always come back and experience more art and the beautiful outdoor gardens.
It all depends on your curiosity in questions about each piece that can take from an hour up to 5 and a 1/2 hours all depends upon you and what you wanna ask questions about.
