This is a great museum! in fact, it is several iin one, and oyu can pick and choose which parts you would like to see, when you purchase the ticket. I recommend to see the entire Palace. Part fo the Palace is an art gallery, which has an amaziing collection, including two outstanding Rembrandt's. Additionally, you can also see the royal apartments, which illustrate how Poland's leaders lived and worked in former times. It is a great experience, and well worth the relatively low cost.
